The climate conference in Glasgow 2021 emphasized the importance of reducing CO2 emissions. This endeavor requires a more significant step towards sustainable energy sources and storage. The rationale for this project is to improve the next generation of emerging solid-state Li batteries (SSLBs), which can eliminate hazards and energy density issues associated with conventional liquid electrolyte-based Li-ion batteries (LIBs). To achieve this goal, five leading research groups and a large technological company in the EU have developed the following strategy to face the current challenges of SSLBs. We rely on multicomponent engineering of cathode material and its interface with the solid-state electrolyte to prevent stress-induced loss of contact during charge/discharge, which degrades electron/ion transfer, and thus improving the SSLB performance and longevity. Potential benefits are seen in the application of SSLB as true alternative to LIB to replace fossil fuels in the car industry.
