ABSTRACT:
In a redox battery including an electrolytic cell which has a circulating type electrolytic solution and an intermittent circulating type electrolytic solution which has a membrane and which employs an electrolytic solution permeable porous electrode, a solution of vanadium (II/III) dissolved in sulfuric acid is used as an active material on the negative electrode of a redox couple, and an oxidizing substance in a gas (such as oxygen) or in electrolytic solution is used as an active material on the positive electrode of the redox couple. The redox battery of the invention shows high energy density, and has a small size and a high output, thus it can be used for an electric vehicle or as a portable battery.
