Planned technological developments and recommendations for action
The focus of SafeLIB is on increasing the safety and reliability of Li-ion batteries used in mobile and stationary applications. A combined, interdisciplinary and cross-sectoral approach leads to a deeper understanding of relevant mechanisms, to improved models and testing procedures, and to comprehensive technical-legal-economic recommendations for action for industry and politics/legislators.
SafeLIB aims to improve the environmental footprint and safety of automotive lithium-ion batteries.
SafeLIB develops efficient methods that significantly reduce the time and effort required to create a validated numerical model and perform extensive parameter investigations.
Furthermore, SafeLIB aims to analyse ageing effects on the mechanical and safety behaviour of LIBs in order to maximise their lifetime and sustainability. For this purpose, state-of-the-art LIBs of different types (prismatic, pouch as well as different chemistry and design/structure) are investigated. In addition, the project also considers the very latest LIB cell technology, i.e., all-solid-state cells, which are expected to provide higher safety and higher energy densities, but still require significant research in terms of their mechanical, electrochemical or ageing behaviour.
Another focus of the project is the scientific investigation of technical and legal/regulatory framework conditions for the qualification and safe continued use of batteries - after their initial use in vehicles ("First Life") - for mobile and stationary Second Life applications.
