PURPOSE:To suppress the internal pressure rise of a hydride secondary battery, improve charge/discharge cycle characteristics, simplify the activation treatment, reduce a self-discharge, and improve the discharge characteristic at a large- current discharge and the discharge characteristic at a low-temperature discharge. CONSTITUTION:A soluble hydride such as sodium borohydride is incorporated in an electrolyte, or a negative electrode is dipped in an alkaline aqueous solution dissolved with the soluble hydride such as the sodium borohydride before a battery is assembled, and the negative electrode is treated with a reducing agent. |
