Abstract

High quality Li₃PO₄ thin films have been prepared by pulsed laser deposition (PLD) as a solid electrolyte for thin-film batteries. The structure, composition, ionic conductivity, and electrochemical stability of the Li₃PO₄ thin films have been characterized. The Li₃PO₄ film exhibits a single lithium-ion conductor with an ionic conductivity of 4.0× 10^-7 S cm^-1 at 25°C and an activation energy of 0.58 eV. The Li₃PO₄ film is electrochemically stable in the potential range from 0 to 4.7 V vs Li/ Li⁺. All-solid-state thin-film batteries, Li/ Li₃ PO ₄/ LiCoO₂, have been fabricated by using PLD-grown Li ₃PO₄ thin film. The thin-film battery shows excellent intercalation property and stability for long-term cycling in the potential range from 3.0 to 4.4 V.
