METAL OXIDE COMPOSITE CATHODE MATERIAL FOR BATTERIES WITH HIGHER ENERGY DENSITY

摘要

An electrochemical cell incorporating a cathode material comprising a mixed oxide of vanadium, silver and copper. The cathode materials of this invention are formed by the chemical addition, reaction, or otherwise intimate contact of various mixed oxides and/or metal elements during thermal treatment in mixed states. A preferred material comprises a composite metal oxide matrix formed as the thermal decomposition and reaction product of a matrix of vanadium oxide and at least decomposable compounds of copper and silver.
