Abstract
320-nm-thick LiZr2(PO4)3 thin film was prepared by radio frequency sputtering and thermally annealed up to 1000°C to fully crystallize the as-deposited film. The room-temperature ionic conductivity of the film annealed at 800°C was 1.3 × 10−7 S/cm which was inferior compared to its bulk counterpart due to the partial crystallization and small grain size; however, at an elevated temperature, the ionic conductivity approached the bulk value, reaching 4.0 × 10−6 S/cm above 100°C. It was demonstrated that combined with chemical stability of LiZr2(PO4)3 and low electronic conductivity, the LiZr2(PO4)3 thin film can be a possible candidate material for a solid electrolyte operating at an elevated temperature.
