PURPOSE:To obtain an electrode having superior mechanical strength, electric conductivity, and electric discharge characteristic by mixing at least one kind among lithium hydroxide, lithium carbonate, and lithium chloride with nickel oxide powder and treating said mixture with press molding and firing. CONSTITUTION:Lithium hydroxide is added in a molar ratio of 1:0.5 into the nickel oxide powder having an average particle diameter of 20mum or less, and a proper amount of water is further added into the above mixture so that an uniform mixture can be obtained. The slurry consisting of aqueous solution of lithium hydroxide and nickel oxide dispersed is dried and coagulated, and then molded to a plate form having a thickness of about 1mm. under a pressure of 300kg/cm<2>, and then said plate is baked at 1,100 deg.C in air for 4hr. Thus, the electrode having a sufficient corrosion resistance enough to stand the use over a long period, high mechanical strength, and superior electric discharge characteristic can be obtained. |
