Antiperovskite Li 3 OCl Superionic Conductor Films for Solid-State Li-Ion Batteries

摘要

Abstract Antiperovskite Li 3 OCl superionic conductor films are prepared via pulsed laser deposition using a composite target. A significantly enhanced ionic conductivity of 2.0 ???? 10 ?￠????4 S cm ?￠????1 at room temperature is achieved, and this value is more than two orders of magnitude higher than that of its bulk counterpart. The applicability of Li 3 OCl as a solid electrolyte for Li-ion batteries is demonstrated.
