PURPOSE:To obtain a silver peroxide cell with a small internal resistance and a low self-discharge rate by adding a conductive agent to a positive electrode compound material and also adding a stabilizer for silver peroxide to an alkali electrolyte. CONSTITUTION:A carbon material as a conductive agent made of graphite powder and carbon black powder, metal powder made of nickel powder and tantalum powder, and alloy powder made of stainless powder are added to silver peroxide powder produced from a silver nitrate aqueous solution, caustic soda, and potassium peroxide, and they are mixed together, then are molded with pressure into a positive electrode compound material 7. Cadmium and tellurium, or cadmium and tellurium and at least one constituent selected among lead, mercury, thallium, germanium, yttrium, tin, tungsten, lanthanum, rare earth elements, zinc, selenium, and aluminum are contained as a stabilizer in an alkali electrolyte, which is impregnated into an electrolyte impregnating material 10. |
