Abstract: A composite electrode is created by forming a thin conformal coating of mixed metal oxides on a highly porous carbon structure. The highly porous carbon structure performs a role in the synthesis of the mixed oxide coating and in providing a three-dimensional, electronically conductive substrate supporting the thin coating of mixed metal oxides. The metal oxide mixture shall include two or more metal oxides. The composite electrode, a process for producing said composite electrode, an electrochemical capacitor and an electrochemical secondary (rechargeable) battery using said composite electrode are disclosed.

Abstract: An oxygen electrode is created by forming a nanoscopic coating or nanoscopic deposits of mixed metal oxides as catalysts on a pre-formed, highly porous binder-free carbon structure. The highly porous carbon structure performs a role in the synthesis of the mixed oxide catalyst deposits as well as in providing a three-dimensional, electronically conductive support for the mixed metal oxide catalyst with a large surface area and desirable pore structure. The metal oxide mixture shall include two or more metal species. The multifunctional oxygen electrode materials, a process for producing the same and a metal oxygen battery using said oxygen electrode materials are disclosed.
