Carbon, cobalt, etc. used as conductive agents in electrodes of alkaline secondary batteries are oxidized by the influence of oxygen generated from the positive electrode. There is a problem in that, during repeated charge and discharge, the conductive agent is oxidized and deteriorated, the conductivity is lost, and the cycle life of the battery is shortened. When hydrogen is enclosed in the alkaline secondary battery, the oxygen generated in the positive electrode is combined with the hydrogen in the battery. Thereby, the oxidative deterioration of the conductive agent contained in the electrode is eliminated. A battery with excellent cycle life characteristics can be obtained. |
