Influence of the microstructure on the electrochemical performance of thin film WO3 cathode

Abstract In this work, WO 3 thin films deposited at different powers and geometries have been evaluated for use as electrodes in thin film batteries. The potential profiles and cycling capacity in lithium electrolyte were investigated. The discharge capacity for samples strongly depends on the deposition conditions, and there is a clear correlation between microstructure and electrochemical performance.
