All-solid-state lithium batteries with long cycle life

Sulfide solid state electrolytes (SSEs) based all-solid-state lithium batteries (ASSLBs) provide candidates for energy storage with high theoretical specific energy and potential safety. However, the reported performance of ASSLBs is still unsatisfactory, which is mainly the cycle life bottleneck needs to be broken. The interface reaction between active materials and sulfide SSEs is one of the most important reasons. Recently, significant progress has been made in terms of cathode, anode, and electrolyte. These results provide hopes for long cycle life ASSLBs.
