Abstract

A vanadium electrolyte for energy storage is generally prepared by dissolving vanadium pentoxide (V₂O₅) in sulfuric acid using oxalic acid ((COOH)₂) as a reducing agent. However, there is a disadvantage that the dissolution rate in the sulfuric acid solution of V₂O₅ is very slow. In this study, a new process for producing vanadium dioxide (VO₂), which has the faster dissolution rate than V₂O₅ in sulfuric acid solution, was developed. Vanadium dioxide (VO₂) could be used in the production of a vanadium electrolyte for energy storage. The process developed in the study has the advantages of being economical and simple as compared to the existing process for producing VO₂ from V₂O₅ using hydrogen or carbon monoxide as a reducing agent.
