Abstract

Antiperovskite Li₃OCl 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 Li₃OCl as a solid electrolyte for Li-ion batteries is demonstrated.
