Embedding Antiperovskite Nanophases into Polymer Hosts Boosts Ionic Conductivity and Interfacial Compliance for All-Solid-State Lithium Metal Batteries

All-solid-state batteries (ASSBs) have emerged as a safer and more energy-dense alternative to conventional liquid-electrolyte batteries. In this study, a composite solid electrolyte (CSE) was developed by incorporating Li3OCl (lithium-rich...
