Catholyte‐Free Composite Cathodes Break the Energy Density Barrier of All‐Solid‐State Lithium Batteries

Carbon Energy, EarlyView.
All‐solid‐state lithium batteries (ASSLBs) with conventional catholyte‐based composite cathodes have a theoretical energy density limit of approximately 400 Wh kg–1 and 900 Wh L–1. The design of catholyte‐free composite cathodes can break this barrier and improve the theoretical energy density up to 500 Wh kg–1 and 1000 Wh L–1. ABSTRACT The gravimetric
