PURPOSE:To stabilize silver peroxide and decrease self discharge rate without increase of internal resistance by minimizing the adding amount of cadmium to silver peroxide in a silver peroxide battery using potassium hydroxide solution as electrolyte. CONSTITUTION:In a silver peroxide battery using silver oxide in a positive electrode 2, 0.005-0.03wt% cadmium and 0.005-0.30wt% tellurium are contained in silver oxide, or 0.005-3.0wt% element selected from lead, mercury, germanium, yttrium, tin, tungsten, lanthanum, rare earth elements, zinc, selenium, or aluminum is contained in silver oxide in addition to cadmium and tellurium. Thereby, a silver peroxide battery whose internal resistance is low and self discharge rate is small is provided. |
