NOVEL 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.
