Roadmapping “Lithium-ion battery LIB 2015“ (LIB 2015-Roadmapping)

funded by the German Federal Ministry for Education and Research (BMBF)

The Fraunhofer Institute for Systems and Innovation Research ISI accompanies the partners of the Innovation Alliance LIB 2015 with a roadmapping process. Within its framework, different battery designs, technological and additional performance characteristics as well as performance requirements in terms of application and market and the market penetration are investigated. This is done from a systemic, product-related perspective. Aspects of sustainability are also taken into account: They include defining and looking into different types of batteries, the availability of raw materials used in lithium-ion batteries as well as recycling, with all aspects being analyzed from the (raw) material perspective. In a concluding assessment, all results are brought together, thus creating the basis for the development of scenarios.

The objective of the project is to investigate aspects of sustainability of lithium-ion batteries and their areas of application and to show the best possible paths and important drivers for the development and commercialization of lithium-ion batteries (with strong links to electric mobility).

A mix of methods is used for the roadmapping process which includes qualitative approaches (e.g. questionnaires, interviews, expert assessments, work-shops, literature analyses) and quantitative parameters (e.g. model calculations within the framework of scenarios with performance parameters such as e.g. energy densities or performance densities). These parameters are incorporated into the roadmap (consisting of a technology roadmap, a product roadmap and a comprehensive roadmap) and are cross-referenced.

The findings gained from this data help to develop scenarios and policy options to indicate potential difficulties (e.g. possible supply shortages of critical raw materials). The objective of the project is also to accompany the work of the funded consortia, return fundamental insights and jointly define potential paths for the future.

Nine roadmaps have been published (see diagram). These are technology roadmaps which adapt a technologically-driven perspective for the technical performance parameters of the respective energy storage system, product roadmaps which look at the demands on the performance parameters from the market perspective and the comprehensive roadmaps which integrate both perspectives and therewith make it possible to identify open challenges and potentials.

The Innovation Alliance “Lithium-ion battery LIB 2015” (LIB 2015) was founded in 2007. It is made up of around 60 project partners from politics, industry and science whose joint aim is to ensure progress in research and development of efficient lithium-ion batteries. Safe and high-capacity lithium-based energy storage is an essential element for the further development of alternative drive concepts for hybrid and electric vehicles. It also plays an important role in expanding regenerative energy technology such as e.g. wind energy. New scientific approaches are necessary to make lithium-ion batteries standard equipment. They are to be developed and implemented within the framework of the project LIB 2015.

The project partners want to optimize the performance and efficiency of lithium-ion batteries on all levels: Higher storage potential, increased reliability, longer lifetime, maximum safety. Based on fundamental research, suitable materials and manufacturing processes are therefore developed and used for cell production. Subsequently, the cells are to be integrated into a complete system, combined with an intelligent battery management system. When the Innovation Alliance LIB 2015 was set up, an industrial consortium of BASF, BOSCH, EVONIK, Li-Tec and VW committed itself to investing 360 million euros in the research and development of lithium-ion batteries in the next few years. This amount is supplemented and complemented by funding of 60 million euros from the Federal Ministry of Education and Research (BMBF).
