Metal-air rechargeable battery needs bifunctional catalytic materials, which involve effective oxygen reduction / evolution reactions at the air electrode at the discharge/charge process. We have so far developed new bifunctional catalytic materials for the air electrode using vanadate glasses without noble-metals and minor metals. In this study, a new bifunctional catalytic material for the air electrode has developed using a conductive vanadate glass containing Co.
