Many researchers in the field of energy storage systems have interest in developing new concepts of the batteries to replace Li-ion batteries. Among these concepts, in particular, rechargeable multivalent metal ion batteries draw an attention because of a potential capacity increase as well as low price of metal resources. However, the divalent metal ions have shown troubles in intercalation into some host materials. In our investigation, a new host candidate, FeV3O8, has been studied as a positive electrode material. It has a tunnel structure, and considered as a promising material for divalent metal ion intercalation. In this study, the synthesis and the electrochemical intercalation properties of FeV3O8 and the structural changes during discharge/charge are presented. |
