Provided are a high-conductivity doped oxide and a use thereof as a battery polar plate additive. Tungsten oxide or molybdenum oxide is used as a precursor, and a controllable metal doping is performed on same such that an oxide material, which has a high conductivity, a high hydrogen evolution potential and a high oxygen evolution potential and can be stably present in a sulfuric acid solution, is formed therefrom. This material can be used as an additive material for the positive electrode and negative electrode of a battery, can effectively decrease the internal resistance of the electrode, improve active material utilization and charge-discharge rate, and at the same time, can stabilize the electrode structure and improve the cycle service life. |
