Method of preparing hydrogen storage electrode through hydrogen storage alloy one-stage heat treatment

The invention relates to a method of preparing hydrogen storage electrode through hydrogen storage alloy one-stage heat treatment and is characterized in that hydrogen storage alloy which is not through heat treatment is used as 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-formingthrough direct rolling; and the formed electrode is placed in a vacuum heat treatment furnace to perform heat treatment. The electrode plate prepared by the method of the invention has lower cost than that prepared by the existing sintering method; and he nickel-metal hydride battery prepared by using the prepared electrode plate is characterized by high rate performance, high discharge plateau,long cycle life and the like and is applicable to fields such as electric tools, electric bicycles, electric motors, electric vehicles and the like.
