A composition for use in an electrochemical redox reaction is described. The composition may comprise a material represented by a general formula MXOor AMXO, where each of A (where present), M, and X independently represents at least one element, O represents oxygen, and each of x (where present) and y represent a number, and an oxide of at least one of various elements, wherein the material and the oxide are cocrystailine, and/or wherein a volume of a crystalline structural unit of the composition may be different than a volume of a crystalline structural unit of the material alone. An electrode comprising such a composition is also described, as is an electrochemical cell comprising such an electrode. A process of preparing a composition for use in an electrochemical redox reaction is also described.

Electrochemical composition and associated technology

The present invention includes an electrochemical redox active material. The electrochemical redox active material includes a cocrystalline metallic compound having a general formula AMOXO.M'O, where A is at least one metallic element selected from a group consisting of alkali metals, M and M&#x2032; 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&#x2266;x&#x2266;1.1, and 0&#x3c;y&#x3c;4.

Cocrystalline metallic compounds and electrochemical redox active material employing the same

A composition for use in an electrochemical redox reaction may comprise a first material represented by MXOor AMXO, where each of A, M, and X independently represents at least one element, O represents oxygen, and each of x and y represent a number, and second material selected from SiC, BN, carbon tube material, carbon fiber material, and an oxide of at least one element. When the first material is represented by MXO, it may be capable of being intercalated with ionic A to form AMXO. At least a portion of the second material may be at least partially distributed within the first material and/or may at least partially coat the first material. An electrode comprising such a composition is also described, as is an electrochemical cell comprising such an electrode. A process of preparing a composition for use in an electrochemical redox reaction is also described.
