description The invention relates to a sintering method of hydrogen storage alloy electrode which is characterized in that hydrogen storage alloy powder is used as active electrode material, nickel-coated steel mesh is used as skeleton material; hydrogen storage alloy powder and nickel-coated steel mesh are used to perform electrode-forming through direct rolling; hydrogen absorption treatment of the formed electrode is perform before sintering process, then sintering process is performed, and finally the dehydrogenation of the electrode is performed. The electrode plate prepared by the method of the invention has high strength and moderate flexibility; the electrode has high capacity, good high rate of charge-discharge performance, high discharge plateau, much higher activation property and less production cost.
