[0028] The making of a nickel electrode 3: Ni(II) hydroxide, catalyst, additive, conductive agent and PTFE with a concentration of 10% are mixed and filled into the foamed nickel containing 99.8% of nickel, and the part 6mm away from the top of the foamed nickel is not Filling material, the above-mentioned filling material and foamed nickel together form nickel electrode 3 and control the thickness of nickel electrode 3 to 0.42mm, and the foamed nickel part that is not filled with material is the reserved foamed nickel part 9;
[0029] The production of b hydrogen electrode 1: using copper mesh as a carrier, the hydrogen storage alloy powder is mechanically rolled on the copper mesh as an electrode sheet, and the thickness of the electrode sheet is controlled to be 0.22mm, and the electrode sheet is then soaked in a concentration of 5%. PTFE, which can effectively prevent the electrode sheet from being corroded by the electrolyte, and the above-mentioned electrode sheet soaked ...
