摘要
研究了在碱性溶液中以硼氢化钾为还原剂对贮合金粉的表面处理对MH/Ni电池性能的影响。结果表明处理明显提高了MH/Ni电池充放电循环寿命和放电平台电位,改善了电池的高倍率放电性能和低温性能。结合以前的工作分析了表面处理对MH/Ni电池性能改善的机理。
The effects of the surface treatment of hydrogen storage alloy powders using KBH4 as reductant in alkaline solution on the performances of MH/Ni battery were investigated. It was found that the surface modification raised the charge/discharge cycle life and discharge voltage,and improved considerably the high - rate dischargeability and low temperature characteristics. The mechanism of effects on the performances of battery was discussed with previous research.
