Battery research at Fraunhofer ISI

Fraunhofer ISI has been active in the field of battery technologies for over ten years. The technological focus of our battery activities is on lithium-ion batteries. However, also alternative battery chemistries and systems that could reach market maturity in the next few years are continuously monitored and analysed.

Fraunhofer ISI's research questions in the field of batteries range from the evaluation of research and development of new battery technologies in the laboratory to suitable funding strategies, technology commercialisation, industrial production, usage phase and finally end-of-life treatment.

Market analysis and forecasts

The description and analysis of battery markets has been one of our major research areas for more than ten years. We not only track emerging markets, but also evaluate and forecast their future development with the help of our methodological toolbox.

We run a comprehensive database covering the entire LIB value chain from materials to applications and recycling. To maintain and improve our database, we continuously track supply chains and actor networks all the way down to regional sales markets for all major battery applications.

Our data basis allows us to address macro economic research questions concerning e.g. global resource availability or investment flows as well as to develop and benchmark business models targeting specific industries and market segments.

For more information, check our latest publications.

Technology roadmapping and benchmarking

New technologies and innovations are created at the interface between research and industry, which is exactly where we are at home. Thanks to our good networking in the European research scene and with many medium-sized and large international companies, we do not only succeed in picking up on technology trends, but also in evaluating them against application and market requirements at the same time.

We regularly organize technology- and application-specific expert workshops or apply our mathematical models to calculate the effects of technological developments or substitutes at the material, battery cell or system level.

Our technology roadmaps, which were developed within the framework of BMBF funding, can be found in the publications section.

    A Roadmap for Solid-State Batteries

    Scan Online-Veröffentlichung Elsevier: A forecast on future raw material demand and recycling potential of lithium-ion batteries in electric vehicles

    Solid-state batteries are considered as a reasonable further development of lithium-ion batteries with liquid electrolytes. On the basis of an analysis of all materials and concept options, a roadmap for solid-state batteries is presented, relying on both literature survey and experts' opinions. Diverse cell concepts with different solid electrolytes may be developed up to the commercial level, yet there are still major uncertainties concerning production routes, safety as well as cost. As one of the key developments, it appears that hybrid material and cell concepts may be particularly successful on the way to commercialization.

    In the General Roadmap Stationary Energy Storage 2030 (available in German only) the technology offer from the Technology Roadmap is compared with selected applications or business models from the Product Roadmap in which the lithium-ion battery is currently used or can be used in the short to medium term. Compared to the reference technology used today, substitution scenarios are developed that show when an alternative technology can achieve an improvement over the respective status quo. The scenarios considered are (1.) decentralised, grid-connected PV battery systems for self-demand optimisation, (2.) multi-purpose self-demand optimisation with larger storage systems together with peak shaving, as well as (3.) direct marketing of renewable energies (on the generation or grid side, e.g. in island grids) and (4.) balancing power. The comparison of the technologies results in a differentiated picture in which very different technical solutions are attractive.

    The battery industry faces the challenge of sustainability, encompassing environmental impact reduction, social responsibility, and governance. In Europe, sustainability involves developing an ecosystem that ensures stability and growth across the battery value chain. This includes securing access to critical raw materials and achieving technological sovereignty. Efforts have been made to localize production, explore European raw material deposits, and implement regulations. However, Europe still relies heavily on non-European sources, highlighting the need for more sustainable solutions and reducing dependency on non-European players.

    Solid-state batteries are considered as a reasonable further development of lithium-ion batteries with liquid electrolytes. On the basis of an analysis of all materials and concept options, a roadmap for solid-state batteries is presented, relying on both literature survey and experts' opinions. Diverse cell concepts with different solid electrolytes may be developed up to the commercial level, yet there are still major uncertainties concerning production routes, safety as well as cost. As one of the key developments, it appears that hybrid material and cell concepts may be particularly successful on the way to commercialization.

    A forecast on future raw material demand and recycling potential of lithium-ion batteries in electric vehicles

    The study focuses on the future demand for electric vehicle battery cathode raw materials lithium, cobalt, nickel, and manganese by considering different technology and growth scenarios. Depending on the growth and technology scenario, the future demand for lithium and cobalt exceeds today's production by up to 8 times in 2040. Nickel exceeds today's production in one scenario. For manganese, future demand in 2040 remains far below today's production.

  • Comparison of alternative battery technologies: technology maturity, market potential and sustainability benefits
    © Fraunhofer ISI

    The growing global demand for batteries is currently covered for the largest part by lithium-ion batteries. However, alternative battery technologies are increasingly coming into focus due to geopolitical dependencies and resource availability. What alternatives to lithium-ion batteries can meet the growing demand, ease the raw material situation and reduce geopolitical dependencies? How can supply chains be established in such a way that a resilient and technologically sovereign battery ecosystem can be created in Europe? And what about sodium-ion batteries, already used in electric vehicles in Asia?

    The cathode is a central component of a lithium-ion battery cell and significantly influences its cost, energy density, i.e. relative storage capacity, and safety. Two materials currently dominate the choice of cathode active materials for lithium-ion batteries: lithium iron phosphate (LFP), which is relatively inexpensive, and nickel-manganese-cobalt (NMC) or nickel-cobalt-alumina (NCA), which are convincing on the market due to their higher energy density, i.e. their ability to store electrical energy. Our analysis shows where in the world how much of which cathode material will be used in battery production and by when.
