Cocrystalline metallic compounds and electrochemical redox active material employing the same

摘要

The present invention includes an electrochemical redox active material. The electrochemical redox active material includes a cocrystalline metallic compound having a general formula AxMO4-yXOy.M′O, where A is at least one metallic element selected from a group consisting of alkali metals, M and M′ may be identical or different and independently of one another at least one selected from a group consisting of transition metals and semimetals, X is P or As, 0.9≦̸x≦̸1.1, and 0<y<4.
