EXECUTIVE SUMMARY
This report “BATTERY SYSTEMS FOR ELECTRIC ENERGY STORAGE ISSUES” represents the position
of the European Battery Industry related to the Research & Technological Development (RTD) needs in the
field of battery systems over the next 10-15 years.

Since the presentation of a first rechargeable battery by Gaston Planté on March 26th, 1860, the
rechargeable batteries used to be considered as a key component of the way of life: they were associated
with the widespread use of electricity as energy sources.

A lot of improvement has been made to cope with the different requirements related to different situations:
• Cranking power for car, aircraft, boat…
• Electrical traction for heavy duty equipment, transport and logistic systems
• Back-up power for emergency systems

The strong impetus of the European Union for Sustainable Development induces challenges on major
issues for the future, especially related to the reduction of greenhouse gas emissions, increased renewable
energy storage, importance of security of energy supply and growing demand for hybrid vehicles.

Within that perspective, electricity is becoming a key energy carrier that requires mandatory storage systems
to match the requirement for easy availability at the point of use:
• Hybrid vehicles based on combustion engines or vehicles with auxiliary or full fuel-cell systems
• New electricity networks based on distributed energy resources like renewable resources
• More Electrical Aircraft based on a widespread use of electric devices instead of mechanical or
    pneumatics
• ....

In order to meet these challenges, the European Industry gathered under the EUROBAT umbrella to:
• Express a battery vision for the future based on two main concepts:
         “Pentagon of Virtues” concept related to the five High-Level Targets that must be taken into account
         to build the battery vision
         “Electrical Energy Storage Systems” (E2S2) concept related to the realisation of the battery vision

•   Outline a Strategic Research Agenda (SRA) for the future based on three main electrochemical
    systems:
        Lead-Acid systems
        Ni/MeH (Nickel-Metal Hydride) systems
        Li-Ion (Lithium- Ion) systems

The considerable RTD effort will strengthen the European Battery value chain composed of the four main
categories:
• Battery Manufacturing Industry
• Battery Suppliers Industry
• Battery Engineering/Service Industry
• Battery Research (public & private)

The mobilisation of this European Battery Network is mandatory to meet the European Sustainable
Development challenges and to face the strong competition coming mainly from Far East countries. All EU
initiatives for Funding and regulatory/legislative proposals need to take into account that a strong
manufacturing base in Europe is a requirement for strong RTD efforts, in support of competitiveness of
industry in Europe.

1   STATE OF THE ART
    1.1 Battery basics

A battery is an energy storing system based on electrochemical charge/discharge reactions. During
discharge the chemical energy is converted into electrical energy and during charge the energy is
reconverted into chemical energy. In a primary battery system only the discharge reaction can be used. A
secondary or rechargeable battery system is characterized by a charge/discharge reaction that is reversible.




The higher the reversibility the more discharge/charge cycles can be performed. The electrical energy stored
in a battery is directly related to the chemical energy being stored. The cathode incorporates an oxidizing
material, the anode a reducing component. The laws of nature have fixed limits to specific energy of
electrochemical systems from the periodic table of elements:




The maximum theoretical specific energy is attained for Lithium and Fluorine at 6,085 Wh/kg. However, most
chemical reactions cannot be used in a battery system because they are not reversible in an electrochemical
cell.

Batteries have to be distinguished from fuel cells and capacitors. A capacitor is based on a reversible
separation of charge with a significant lower energy, compared to a chemical reaction associated with a
battery technology. Fuel cells convert chemical energy into electrical energy without the ability to be
recharged by electrical power. Whenever energy has to be reversibly discharged and recharged at high
energy density, and with high efficiency, a battery is the most suitable energy storage system.




                                                                                                           4
    1.2 Main Battery technologies

Although a broad range of different electrochemical systems and battery technologies exists today three
systems dominate the current market:
       Lead-Acid battery technology
       Alkaline battery technology
       Lithium Ion battery technology

The selection of one of these technologies depends on the requirements regarding performance, life, safety
and cost. As described in Section 2, the selection of the battery system depends on the application.

        1.2.1 Lead-Acid battery technology

The lead-acid technology is the most widely used electrochemical system.

The lead-acid battery is based on:
       Lead dioxide as the active material of the positive electrode,
       Metallic lead, in a high-surface-area porous structure, as the negative active material,
       Sulphuric acid solution.

In fact, lead-acid technology is composed of several sub-technologies according to the battery design and
the manufacturing process:
          Flooded lead-acid batteries,
          Valve-Regulated Lead-Acid (VRLA) batteries with electrolyte immobilized by a gel,
          VRLA batteries with the electrolyte immobilized in an absorptive glass mat (AGM)




                                                                                                             5
        1.2.2 Alkaline batteries

Rechargeable alkaline batteries employ a nickel hydroxide based cathode, with either a metallic anode
(Nickel-Cadmium (Ni/Cd), Nickel-Iron (Ni/Fe), Nickel-Zinc (Ni/Zn) or a hydrogen storing anode (Nickel/H2,
Nickel-Metal Hydride (Ni/MeH)). Due to technical limitations on maintenance and long term cycling
performance, Ni/Fe and Ni/Zn batteries cannot be used for automotive or stationary applications. Ni/MeH is
technically superior to Ni/Cd in a number of technical aspects and it can be used in many applications.




Nickel/Hydrogen (Ni/H) and Ni/MeH batteries, in principle, represent the same battery system, namely nickel
hydroxide (NiOOH) as positive and hydrogen (H2) as negative electrode materials. In Ni/MeH batteries a
hydrogen storage alloy is used. Both systems have excellent cycle life.

        1.2.3 Lithium-Ion batteries

Lithium-Ion (Li-Ion) is the dominating battery system for current portable applications. It was introduced to
the market by SONY in 1991. Due to the high capacity of active materials and a single cell voltage of 3.6V,
Li-Ion provides the highest energy density of all rechargeable systems operating at room temperature. Li-Ion
provides approximately twice the specific energy of Ni/MeH and three times the specific energy of lead-acid
batteries. Li-Ion batteries are also available as lithium polymer batteries using a solid or gel-type electrolyte.

The Li-Ion battery employs a Lithium metal oxide cathode and a carbon anode with an organic electrolyte.
Over the last years tremendous improvements on battery parameters have been achieved. Both the high
level of energy and power makes the Li-Ion system very suitable for various applications, ranging from high
energy to high power. The high single cell voltage not only results in high performance, but also allows the
use of a fewer cells, compared to other battery systems.




                                                                                                                 6
    1.3 Other battery technologies

        1.3.1 High Temperature systems

There are three different high temperature systems which have gained some attention as electrochemical
energy storage systems; Sodium / Sulphur (Na/S), Sodium / Nickel chloride (Na / NiCl2) and Lithium / Iron
sulphide system (Li/FeS). The common feature of all these systems is an operation temperature of more
than 300°C, which necessitates permanent heating to remain functional. The High temperature systems
need high integrity ceramics for separation, a corrosion resistant case and sealing materials, and an
excellent thermal insulation for limiting the heat losses. Originally provided for energy storage in electric
vehicles in large volumes, they are only playing a role in certain niche markets (UPS, electric and hybrid
buses). Permanent heat losses may lead to a poor energy balance (charged energy against dischargeable
energy), particularly for those applications, which are not in permanent operation.

        1.3.2 Metal Air systems

Metal Air systems have been playing an important role for primary batteries. The anode material consists of
a highly porous metal powder and the cathode is a carbon based material capable of electrochemically
converting ambient air into oxygen. The Zinc / Air system (e.g. batteries for hearing aids) and the Aluminium
/ Air system (emergency systems) have achieved a commercial importance. Metal Air systems may even be
designed as rechargeable. However, the recharge must be done by mechanically removing and replacing
the spent anode. The anode may be recovered by an external chemical process before re-use. It is mainly
the impracticality of the metal electrode exchange process and the associated high costs, which have kept
the metal air systems from a breakthrough in the rechargeable battery market.

2 BATTERY APPLICATIONS
Batteries are the principal method of storing electrical energy. Different energy storage technologies are
shown below:




Batteries are a key technology for the efficient and sustainable use of electrical energy in current and future
applications.

    2.1 Current applications

Current applications can be divided into three main categories:
        Automotive applications.
        Industrial applications.
        Portable applications.

        2.1.1 Automotive applications

The automotive applications are mainly related to “Start, Lighting and Ignition” (SLI) batteries.
The battery functions are to provide:

        High power for a very short time to start the engine.
        A low power supply for electrical devices when the engine is stopped.

Batteries are also included in automotive power trains for:

        Electric Vehicles using electricity instead of gas or diesel for motive power.
        Hybrid Vehicles based on a combination of electric and internal combustion engines.




                                                                                                                  9
        2.1.2 Industrial Applications

Industrial applications are mainly in the two following categories:

        Stationary applications: batteries are used to provide electrical power to systems during instances of
        power outages for:

        •   Telecommunication networks
        •   Emergency lighting applications
        •   Data communication systems
        •   Security systems

        Transport applications: batteries are used to provide electrical energy for specific vehicles:

        •   Electrical traction for Heavy-Duty equipment (utility vehicles, tow tractors, trucks, passenger
            carriers, material handling equipment, floor scrubbers, airport ground equipments and other light
            vehicles such as golf carts, wheelchairs).
        •   Cranking power for aircraft, railway locomotives and boats. Railroad equipment: railroad
            crossing lights, gates and signals.
        •   Security energy for railway equipment, aircraft equipment.




    2.2 Future applications

Batteries will be a key technology to enable many new systems to be brought into effective use including:

        Energy systems:

        •   Fuel Cell system operation is optimized with a battery.
        •   Solar Systems and Wind Energy Systems have an output that is too variable to be used without
            batteries.
        •   New ” Distributed Energy Resources “ (DER) networks will need energy storage to balance
            energy supply and energy use.

        Transport Systems:

        •   Clean vehicles will be based on a more intensive use of electricity.
                o Hybrid or electrical power trains using batteries.
                o Replacement of mechanical devices by electrical devices, leading to an increased use
                   of electricity and to more efficient batteries.

        •   Aeronautics intends to develop “More Electrical Aircraft”, which will require innovative batteries.
        •   Electrical ship propulsion concepts will be introduced in the next few years.

        Information and Communications:

        New communication networks (fixed, mobile, wireless, broad-casting networks) will require
        innovative battery solutions to guarantee service availability in all conditions.




                                                                                                              10
       Health:

       •   New health therapies will be based on the use of electrical devices that will require batteries for
           operational security.

       Space:

       •   As weight and volume are expected to continue to be a key issue for satellite systems, new
           smaller and lighter batteries will be required to support the development of this market.

       Security:

       •   Security of infrastructure provided by utilities is expected to be one of the main challenges over
           the coming years: increased use of batteries will make an important contribution to ensure the
           security of the electricity network without excess generating and distribution capacity.




3 EUROPEAN BATTERY NETWORK
The European Battery Network is composed of the following parts:

           European Battery Industry.
           European Battery Suppliers.
           European Battery Service Structure.
           European Battery Research.




                                                                                                             11
             European Battery Industry

The worldwide rechargeable battery market had a value of 19 B€ in 2004. This market is composed of 3
different segments and is based on 4 main battery technologies, as shown below:




The European Battery Industry is based primarily on the Automotive & Industrial markets, which are
dominated by Lead-Acid technology, with the use of Ni/Cd technology for specific applications as shown
below:




The European Battery Industry employs 40,000 people located in most European countries, and is
comprised of several companies involved in a number of battery technologies (see table below):

    3.1 European Battery Suppliers

The Battery Industry depends on European suppliers carrying out research and development to provide
innovative components but, unfortunately, the trend is that the number of European suppliers and their
efforts are decreasing.

For lead-acid batteries, the production of lead and alloys both from primary and secondary resources is
important. The principal use of lead is in batteries and the principal source of secondary lead is end-of-life
batteries. There is a highly effective recycling network and lead is the most efficiently recycled commodity
metal. Other main suppliers are plastic moulders for battery containers, suppliers of chemicals and special
manufacturers of micro-porous plastics and papers for battery separators.

For Nickel-based batteries, the production of special forms of nickel and nickel compounds is important not
only for the European industry, but for the industry worldwide.

Lithium batteries also use micro-porous materials for battery separators. There are also European suppliers
for carbon compounds, metal oxides and electrolytes.

For non-lead/acid rechargeable batteries a substantial recycling industry is in place to ensure that materials
of value are recovered for reuse and that materials are not dispersed into the environment at end-of-life. It is
important for the suppliers to maintain a healthy European industry, which in turn gives them a base from
which to expand their business globally.

    3.2 European Battery Services

In addition to a well-functioning supply structure and the availability of appropriate manufacturing
technology, the European battery industry is also dependent on a highly effective system for distribution and
service. This not only includes commercial supply and distribution structures, but also the needs of high-level
technical support and service.

All applications of rechargeable battery systems need to be supported by technical advice and by expert
engineers for each type of duty. This type of service is essential for the optimum operation of battery
systems and for customer satisfaction and safety. Systems in operation without suitable control devices are
not only uneconomical, due to early failure and low efficiency, but may be a safety hazard. This is especially
true for batteries used in safety sensitive fields (UPS systems, automotive applications). For that reason, the
European Battery Industry needs to have a sufficient number of well-trained experts available. Basic
technical knowledge about battery systems is necessary to find the most technically suitable solution for
each particular application.

Moreover, the experts and the network they provide will give technical feedback to research and
development, thus triggering the continuation of technical progress in this important technical area and
business.

    3.3 European Battery Research

European battery research is mainly performed in battery company R&D centres and in publicly funded
laboratories.

The industrial research centres are located across Europe, as shown below:




Publicly funded research laboratories are mainly involved in lithium technology and there are participants in
many European countries, as shown below:




                                                                                                            14
4 BATTERY CONTRIBUTION TO EUROPEAN SUSTAINABLE DEVELOPMENT
  STRATEGY
Sustainable Development was defined by the Bruntland Commission (1987 Report “Our Common Future”)
as “the development that meets the needs of the present without compromising the ability of future
generations to meet their own needs”.

In 2001 the European Commission issued its first strategy for sustainable development, linked to the work of
the European Environment Advisory Councils (EEAC). A working group was established to state “Green
sustainable development strategies” with the underlying message that, in the longer term, a healthy
environment is fundamental to economic development and human welfare. They should also define a
framework for integrating environmental consideration into EU policies in every sector, in addition to
economic and social indicators.

The EEAC then proposed significant changes to policies in several sectors, which in some cases are directly
related to the battery/energy storage industry, such as:

        Energy:         A need for very large reduction of CO2 emissions in the long term.
                        Structure energy markets to encourage low-carbon technologies.

        Transport:      More ambitious targets to reduce fuel consumption of vehicles
                        Measures to promote less environmentally damaging forms of transport.

    4.1 Batteries and Sustainable Energy Policies

According to the Kyoto protocol, the EU is committed to reduce its greenhouse gas emissions by 8% as
compared to 1990. Moreover, 94% of CO2 from human activities can be attributed to the energy sector,
whereas 90% of the increase is attributable to road transport. On the other hand, according to the green
paper “towards a European Strategy for the security of energy supply”, which considers the growth of energy
needs and the dependence on external energy supply sources, the EU has set a target that, in 2010, 12% of
the total energy consumption should be from renewable resources.

Due to the intermittent nature of many renewable energies, and the need to adjust energy supply to energy
consumption peaks, energy storage is a key issue in the achievement of these targets. Batteries, as
autonomous and well proved electrochemical energy storage systems, are enabling technologies for future
sustainable energy systems, characterized by a higher integration of Renewable Energy Systems (RES) into
grids and decentralized generation. Batteries can contribute to solving the following key issues:

        Intermittent nature of RES.
        Load leveling (peak consumption).
        Power quality management.
        Voltage and frequency support.
        Reserve capacity and emergency supply.
        Supply power peaks in hybrid systems with stationary fuel cells.

    4.2 Batteries and Sustainable Transport Policies

Within the generic target of promoting clean urban transport, hybrid vehicles, both with conventional internal
combustion engine (ICE) engines in the short-medium term, or powered by a fuel cell in the long term,
appear in the EUCAR-CONCAWE-JRC report “Well-to-Wheels Analysis for future Automotive Fuels and
Power-Trains in the European Context” as the best option to achieve further fuel consumption and
emissions reductions. In both cases, the battery is a key element providing energy at start and acceleration,
and to recovering energy during braking, as well as supplying energy to all vehicle consumers during stop
and idling periods. The step leading to success in hybrid vehicles is on the short to mid-term because of the
increasing oil prices and lower costs of components.




                                                                                                            15
    4.3 Batteries and Social & Employment Policies

Batteries represent, at the present time, the main solution to energy storage needs in a widespread number
of autonomous applications, from vehicles and portable devices to RES systems, through a variety of
industrial uses, mainly related to assuring energy supply in cases of mains failure (UPS,
telecommunications), as well as in strategic defense applications. For this reason, batteries are key
technologies for many European strategic industrial sectors, in which social welfare and employment are key
issues.

The ability to continue or further increase research and deployment of the new technologies is highly
dependent on a strong manufacturing base for batteries in Europe. This sustainable industrial base is a
requirement for continued RTD efforts by companies in Europe, which in turn supports the competitiveness
of the industry in Europe in sectors much wider, namely those that incorporate batteries as an essential part
of their electronic and electrical technology. Finally this will benefit European employees and consumers.

    4.4 Battery and Environmental Health & Safety Policy

The European Battery Industry has fully endorsed the principles of the European environmental policy:

        Set up of closed-loops systems, which already ensure a very high level of collection and recovery
        rates for automotive & industrial batteries.
        Decreasing the environmental impact of resources use and waste.
        Decreasing energy and material consumption.

Over the years the industry has issued statements regarding its excellent environmental responsibility and
sound product stewardship. The high quality of production and outstanding level of recycling of batteries and
their components has been underlined in several ways. This performance and continue need for industrial
and automotive batteries are recognized by the European Council of Ministers, in their adoption of the text of
a new draft Battery Directive in First Reading on 20 December 2004.

The Life Cycle of the product needs to take into account the safe production, which is covered by stringent
regulations for worker’s health and safety in the battery industry across Europe and with strict
implementation of those rules. Via EUROBAT the manufacturers and recyclers have also contributed
significantly to positive quantitative and qualitative aspects of the multi-annual project of the Voluntary Risk
Assessment for Lead under the leadership of the LDAI, and reviewed by the Member States. The draft
report will be published in 2005 and is scheduled for finalization in 2006.

The advantages of batteries also apply from an environmental viewpoint to the fact that there are no
emissions from batteries during it useful life. In addition, there are collection and recycling systems are in
place since decades. The value of the materials in the automotive and industrial batteries at the end of their
life is sufficiently high to cover all the costs of collection & recycling. The battery industry has promoted these
aspects and some battery producers have also implemented the theory by operating the recycling facilities
for the lead acid and nickel-cadmium automotive and industrial batteries. The recycling process is state of
the art and in conformance with the EU rules for Best Available Technology. The recovery of the lead
preserves crucial natural resources. It is noted that relatively low energy consumption is needed for the
conversion into secondary lead as a material for new products.

The use of batteries should be placed also in the context of the sustainable development (environmental,
economic and social) goals of the EU. Key examples are the new and emerging applications of batteries in
hybrid vehicles, electric vehicles or vehicles powered by fuel cells for the reason of reducing emissions, or
avoiding of local emissions. The industrial batteries, as stated elsewhere in the report, are an important
power supply in rural areas (solar panels, wind energy, hydropower). They are also used for standby
in control devices e.g. for filter systems, waste water plants, safe running of industrial processes, hospitals,
emergency control rooms and transport security and safety.

The development of battery technologies will bring more efficient batteries to the market.




                                                                                                                   16
5 SUPPORT FOR BATTERY RESEARCH DEVELOPMENT WITHIN PREVIOUS
  EUROPEAN FRAMEWORK PROGRAMMES
    5.1 Position of Energy Storage RTD in the European Framework Programmes

As energy storage is considered as a key enabling technology for the development of sustainable energy
systems, the EU has funded RTD on energy storage for stationary and transport applications through
successive Framework Programmes (FP2 to FP6).

However, if the structure of the previous FP allowed the European Battery Industry to develop innovative
solutions for different battery issues (materials, manufacturing process, system integration), the focus of the
current FP6 on a limited number of thematic priorities makes it very difficult for the European Battery
Industry to be involved, especially in the first FP6 calls.

    5.2 Battery RTD in FP4

Most of battery RTD projects were funded in the Joule programme and concerned materials, processes and
components for energy storage as well as energy storage systems integration: 29 M€ were allocated to 19
projects on energy storage, of which 21 M€ were allocated to 12 projects for research on advanced batteries
(mainly lithium and lithium polymer).




Other FP4 programmes contributed to battery development such as Brite-Euram programmes (innovative
battery materials) or Thermie programmes (demonstration) for example.

The main result was the qualification of Li-Ion technology for industrial and automotive application
demonstrated with the road tests performed by FIAT and DaimlerChrysler on electric vehicles:




                                                                                                              17
    5.3 Battery RTD in FP5

Most of the battery RTD projects were funded in the “Energy, Environment and Sustainable Development
Programme” (EESD). Target action related to energy storage.

21 M€ were allocated to 20 projects on energy storage, of which 18 M€ were allocated to 15 projects related
to battery or battery related technologies.

Other FP5 programmes contributed to battery development, such as Growth (Competitive & Sustainable
Growth) programmes for road transport applications.

These projects were related to research & development on battery systems for hybrid vehicles and for the
integration of distributed energy resources, such as renewable energy sources (RES).

The following projects had important results:

        INVESTIRE: the European Battery Industry participated in a network to evaluate the current and
        future energy storage technologies for intermittent RES applications and to define a RTD road map.




        ABLE: an advanced storage system for small & medium-sized PV systems based on an innovative
        design of lead-acid battery, was studied and testes.

        Li-ion-HEART: this project is related to the continuation of the Lithium RTD efforts performed in the
        FP4 to study an innovative battery system architecture for hybrid vehicles.




                                                                                                            18
    5.4 Battery RTD in FP6

The FP6 structure is very different to the previous FPs, with focus on some thematic priorities.

New electricity networks based on Distributed Energy Resources (DER) are considered to be a priority, but
the energy storage technologies are only components of this new concept.

However, as the DER networks face many issues and are expected to be implemented in a medium-long
term timeframe, the FP6 RTD programmes have concentrated industrial efforts on DER implementation
issues, and have only studied the energy storage integration issue.

Battery research is only performed in a network of excellence (ALISTORE), which gathers the main
European research centers to study advanced lithium battery systems based on the use of nano-materials: a
breakthrough is being researched for the 2025 time frame, but nothing is foreseen in the intermediate future.

The FP6 situation is completely different to FP4 and FP5, which supported industrial RTD on batteries: 39
M€ was allocated to various different topics (see below):




The first half of FP6 shows a large reduction of funding for battery development compared to previous FPs
as below:




                                                                                                            19
6 BATTERY CHALLENGE FOR THE FUTURE
    6.1 Principles

The strong concern of the EU for Sustainable Development leads to wide challenges on major issues for the
future:

        Growing concerns on the emission of greenhouse gases since the Kyoto protocol which has been
        signed by EU,

        Raised questions on the security of the energy supply in Europe due to the increasing dependence
        on oil (70% in 2030),

        Stronger public opinion on waste issues to be considered from the point of view of product life
        cycles.

Within that perspective, electricity is a key energy form, but it does require storage systems to match the
requirement for easy availability at the point of use.

So, the battery challenge for the future will be to contribute to a widespread use of electricity in a
way compatible with the economic and environmental requirements.


The battery challenge must cope with two different situations:

        Stationary situation: the Battery Industry will have to provide innovative solutions at the following
        three levels:

        •   Production of electricity in order to reach high quality standards.
        •   Electricity network in order to guarantee a permanent supply of energy.
        •   Customer level in order to customize the standard electricity service to specific situations:
            medical environments, high technology processes, isolated locations.

        Mobile situations: the mobile human being must be able to use electricity for two main applications:

        •   Propulsion application: electricity use contributes simultaneously to decrease the emission of
            greenhouse gases and to safeguard fossil based energy.
        •   Supply of on-board equipment: automotive power networks, engine starting.

In particular, the Battery Industry will face strong challenges in the following areas:

        Energy
        Transport
        Customer service


    6.2 Energy Area

The battery industry challenges are related to the use of new electricity generation systems and the
installation of new electricity networks.

        6.2.2 New Electricity Networks

New electricity networks will be based on the integration of renewable energy sources (RES) and distributed
generation (DG): integrated or stand-alone use of small, modular energy conversion units close to the point
of consumption.

Two types of electricity grids are envisaged:

        Large grids related to widespread electrical distribution systems.




                                                                                                           21

    6.3 Transport Area

Battery challenges are mainly related to the “greening of the different transport systems”:

        Air transport system: reduction of emissions by using “more electrical” aircraft.
        Road transport systems: reduction of emissions and fuel consumption by using hybrid propulsion
        systems (FC based or ICE based) or pure electrical propulsion.
        Rail transport systems: reduction of emissions or energy consumption by better energy
        management.

7   LINKS WITH IDENTIFIED TECHNOLOGY PLATFORMS
    7.1 Background

The major economic, technological or societal challenge with which Europe is faced, are illustrated by the
emergence of Technology Platforms (TPs).

The different TPs define RTD priorities for a number of strategically important issues with high societal
relevance where achieving Europe’s future growth, competitiveness and sustainable objectives are
dependant upon major research and technological advances in the medium to long term.

Some of the current TPs are expected to need energy storage to take up their challenges, while others, on
the contrary, are expected to help the energy storage to reach their objectives.

Some links will be set up with both categories of TPs to define the relevant strategic research agenda (SRA):

        Battery RTD can only be carried out for identified applications.
        Battery RTD is dependant on generic technologies: for example manufacturing processes, nano-
        technologies.




                                                                                                             23
    7.2 TPs Requiring Energy Storage

The following TPs are expected to use battery systems as key enabling technologies:

        HYDROGEN AND FUEL CELLS: (transport, grid or portable applications)
        Due to the preferred constant working regime for fuel cells, and the high investment costs to
        dimension fuel cells for peak power needs, batteries are the complementary storage devices, both
        for peak power demands and to store energy generated and not used immediately.

        ROAD TRANSPORT (ERTRAC):
        Batteries are key components in hybrid electric vehicles, aimed at storing energy that is generated
        during regenerative braking and assisting the ICE during start and acceleration.

        RAIL TRANSPORT (ERRAC):
        Efficient use of energy by the rail transport operators needs to use batteries for recovering all energy
        available during the operations (braking energy recovery), on board Energy Storage and energy
        storage in Sub-stations.

        MARITIME TRANSPORT (ACMARE):
        High performance battery systems are expected to allow the development of electrically powered
        ships.

        AERONAUTICS (ACARE):
        The development of the “More Electrical Aircraft” concept is expected to derive benefit from the use
        of high performance batteries for the new electric network.

        THE EUROPEAN SPACE TECHNOLOGY PLATFORM:
        Battery system use is essential to supply the satellite equipment.

        EUROPEAN PHOTOVOLTAICS TECHNOLOGY PLATFORM:
        Batteries will be needed for energy storage to cover periods of insufficient supply situations and to
        improve system efficiency and power quality.

        EUROPEAN WIND ENERGY PLATFORM:
        Batteries will be needed for energy storage to cover periods of insufficient wind and to offer high
        quality electricity to the network.

        ELECTRICITY NETWORKS OF THE FUTURE:
        Batteries may serve as an important medium for storing energy and stabilizing the networks.

        MOBILE COMMUNICATIONS TECHNOLOGY PLATFORM:
        Batteries supply energy to keep communication systems working in remote areas. Battery
        performance should be improved to increase reliability and life under extreme environmental
        conditions.

        BUILDING FOR A FUTURE EUROPE:
        In conjunction with PV and FC systems, batteries will be used in the building of the future to store
        and provide energy.


    7.3 TPs Contributing to Energy Storage Development

The following TPs are expected to help the Battery Industry to meet its challenges:

       TECHNOLOGY PLATFORM ON SUSTAINABLE CHEMISTRY:
The development of new materials (nano-technology based, for example) is considered the basis for
improvements in battery performance.

        MANUFACTURING TECHNOLOGIES:
The industry has already achieved a good level of efficiency, but it can be improved with new manufacturing
technologies, which are vital to remain competitive against Asian suppliers.


                                                                                                                24
8 BATTERY VISION FOR THE FUTURE: 2020
    8.1 Vision

The battery vision for the future is based on customer needs: “Electrical Energy Storage System” (E2S2),
which provides the user with energy at all times when energy is needed, in an economical and environment-
friendly way.

The "Smart Battery" of the future will be able to predict the ability of the electrochemistry to perform
adequately under the application requirements by determining the so called SOF (State of Function), which
is related to the SOC (State of Charge) and the SOH (State of Health) information. The SOF will give a
prediction of available capacity and discharge and recharge capability, thereby allowing a "Smart Battery” to
forecast the response of the electrochemistry to the application demands.

Therefore, in the future, the customer will not have to worry about restrictions of the system or which
technology is applied. The “Smart Battery” will be a so called “Black box” system in the form of an intelligent
energy supply and storage system built into different technologies, for example, hybrid systems in various
combinations of existing battery systems, fuel cells, supercapacitors and equipped with the necessary
electronics, in the form of controller, management and monitoring systems.

The optimal utilization of the “Smart Battery” regarding the performance and lifetime, and therefore a better
overall energy management within the application, is guaranteed in the future.

The battery vision is based on the two following concepts:

        A “Pentagon of Virtues” concept related to the five high-level targets that must be taken into account
        to build the battery vision
        “E2S2” concept related to the realization of the battery vision


    8.2 “Pentagon of Virtues”

For each application, the battery of the future will have to optimize the “Pentagon of Virtues” based on the
five following high-level targets:




                                                                                                                25
        8.2.1 Performance

According to different situations, the performance issue is based on the following criteria:

PERFORMANCE CRITERIA                        DEFINITION
Energy density                              Available energy per litre or kilogram
Power density                               Available power per litre or kilogram
                                            Speed with which the energy or the power has to be released or
Response time
                                            absorbed
Operating constraints                       Climatic conditions, temperature, safety, size, voltage
Shape                                       Strong requirements on battery shape: thickness
Lifetime                                    Cycling or calendar life
Efficiency                                  Energy losses related to the battery operation

        8.2.2 Reliability

The unexpected failure of a battery system cannot be accepted in the future: the customer must be informed
continuously about the state of health (SOH) and the state of charge (SOC) of the battery.

The battery performance must be preserved during the life of the application: maintenance processes must
be reduced to a minimum.

        8.2.3 Industrial processes

The industrial process is key for the battery performance, for battery reliability and for environmental control:
it also has a large impact on battery cost.

Any slight modification to the electrochemistry will lead to a more or less important modification in the
process: it could prevent the right product being provided to the right application.

Industrial Safety is also a key issue for the Battery Industry: occupational health and safety of the workers
and environmental safety, including prevention of major accidents and protection of the environment.

        8.2.4 Environment

The environment issues are related to all stages of the battery life-cycle:




Cost

Battery cost represents the consequence of the four previous issues of the “Pentagon of Virtues”: the main
challenge will be to offer a battery solution suitable to all situations from the economic point of view.




                                                                                                                26
    8.3 “E2S2” concept

In order to fulfil the different requirements, the European Battery Industry will have to provide “Electrical
Energy Storage Systems” (E2S2) instead of cells or modules.

The E2S2 is composed of four functional parts, as shown below:




           Electrochemical system: assembling of electrochemical cells or modules
           Application interface: communication with the application
           User interface: man-machine interface
           Energy management: management of the E2S2

    8.4 Electrochemical Systems

Different electrochemical systems can be used but only three of them are expected to be able to take up the
energy storage challenges, as in the table below:

  Electrochemical                                                                             Improvement

                                          High energy & high
  Li-Ion                  Portable                                    High cost               *****
                                          power
  Na/NiCl2                                High energy                 Low efficiency          *

The three electrochemical systems candidate for the future are expected to be:

           Lead-Acid.
           Ni/MeH.
           Li-Ion.




                                                                                                                27
9 STRATEGIC RESEARCH AGENDA (SRA)
    9.1 Vision

In order for this vision to be achieved, many very encouraging but scattered developments need to be
shaped into a coherent long-term and market-oriented strategy, accompanied by a set of specific transitional
actions: in particular, as batteries are already considered to be a key component of some TPs, or as
batteries can expect to benefit from the results of some TPs, the battery programme will have to be co-
ordinated with the relevant research programmes.

In addition, since the battery used to be considered as a commodity product that can be bought off the shelf,
it is absolutely essential to involve the Battery Industry at the early stages of development, in order to be
able to provide the right component in time.

This research effort will be based on the following actions:

        Basic research: focusing on promising materials, new electrochemical concepts, new manufacturing
        processes and new system architecture.
        Applied research and development: results of the basic research should be critically assessed for
        their industrial potential, and materials, concepts and processes have to be transferred effectively
        and rapidly to a prototyping level, according to manufacturing needs.
        Demonstration: related to the interested TPs.
        Supporting research: providing support in the socio-economic, standardization, quality assurance
        and environmental areas.

This effort will gather the Research Community (Universities, Research Institutes, Private Research),
Industry (Battery Manufacturers, Battery Material Suppliers, Electronic/Engineering, Specialists,
Collecting/Recycling Organizations) and Regulatory Bodies (Standardization, Environment, Security).

The Battery Strategic Research Agenda (SRA) is driven, for each electrochemical system by:

        The five major challenges that interact in addressing its overall objectives.
        The requests expressed by the relevant TPs for the different applications.




                                                                                                           28
