ALKALINE SECONDARY BATTERY

摘要

Carbon or cobalt used as a conductive agent in an electrode in an alkaline secondary battery is affected by oxygen generated from a positive electrode and oxidizes. The issue exists that electrical conductivity is lost and battery cycle life is shortened when a conductive agent oxidatively degenerates during repeated charging and discharging. If hydrogen is sealed inside the alkaline secondary battery, hydrogen generated by the positive electrode will bond with the hydrogen inside the battery. As a result, the conductive agent included in the electrode will no longer oxidatively degrade. A battery having excellent cycle life characteristics can be achieved.
