Thin Film Copper Vanadium Oxide Electrodes for Thermal Batteries

Abstract

In this work, thin film copper vanadium oxide electrodes including Cu3V2O8 and Cu5V2O10 were prepared by an aqueous process for thermal batteries. The electrochemical performances of thin film electrodes were tested and evaluated in thermal cells. Comparing with pressed pellet electrodes, the thin film electrodes were able to deliver higher specific capacities. Without any organic solvent and binder, the process for making the film electrodes is low cost and environmental benign.
