【摘要】 分析了MH-Ni电池产生内压的原因,通过对MH负极配方用粘合剂及合金粉制作工艺的研究,发现负极采用HEC及PTFE做粘合剂和采用热处理合金粉能降低MH-Ni电池1C过充电时的内压,提高电池的循环寿命。

【Abstract】 The causes of producing MH-Ni battery internal pressure were analyzed; binders for MH eletrode and manufacure process of hydrogen storage alloy powder were studied in this paper.It was found that MH electrode containing HEC and PTFE as binders and heattreatment hydogen storage alloy ponwder could reduce MH-Ni battery internal pressure when overcharging at 1C rate, and increase MH-Ni battery cycle life.
