DOPED CONDUCTIVE OXIDES, AND IMPROVED ELECTRODES FOR ELECTROCHEMICAL ENERGY STORAGE DEVICES BASED ON THIS MATERIAL

摘要

The object of the present invention is to provide a class of novel highly conductive doped oxides and their use as an electrode plate additive for batteries. With tungsten oxide or molybdenum oxide as the precursor, the controllable metal doping leads to the formation of highly conductive oxide materials with high hydrogen evolution and high oxygen evolution potential, and can be stable in the sulfuric acid solution. This material can be used as additive materials for the battery positive and negative electrodes and can effectively reduce the electrode internal resistance, improve the utilization efficiency of active materials, increase charge and discharge rate performance, stabilize the electrode structure and improve cycling life.
