HYDROGEN STORAGE BATTERY, POSITIVE NICKEL ELECTRODE, POSITIVE ELECTRODE ACTIVE MATERIAL, AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a hydrogen storage battery with an improved cycle life and a method for manufacturing the same.SOLUTION: The battery has a negative electrode with an electrochemically active negative material and a negative electrode capacity and a positive electrode electrochemically coupled with the negative electrode, the positive electrode having a positive electrode capacity and an electrochemically active positive material with a precharge. Also there is described herein a positive electrode material for a hydrogen storage battery and a method for manufacturing the same. The positive electrode material includes a preoxidized active positive material which is partially non-oxidized. The preoxidized material may be used to provide a precharge to the positive electrode.
