High-entropy battery materials: Revolutionizing energy storage
SSEs for energy storage in all–solid–state lithium batteries (ASSLBs) are a relatively new concept, with modern synthesis techniques for HEBMs are often based on these materials. The development of SSEs dates back to the 1830s when Michael Faraday discovered the first SSE (Ag 2 S and PbF 2 ) [88] (see Fig. 2 A).
