Li-Rich Antiperovskite/Nitrile Butadiene Rubber Composite Electrolyte for Sheet-Type Solid-State Lithium Metal Battery

Lithium-rich antiperovskites (LiRAPs) hold great promise to be the choice of solid-state electrolytes (SSEs) owing to their high ionic conductivity, low activation energy, and low cost. However, processing sheet-type solid-state Li metal batteries (SSLiB) with LiRAPs remains challenging due to the l...

The as-prepared LOCB/NBR CPE film exhibits an improved critical current of 0.4 mA cm−2 and can stably cycle for over 1000 h at 0.04 mA cm−2 under 60°C.
