| 摘 要： | 比较了各种倍率恒流充电和脉冲充电过程中N i-MH电池的温度和内压,进行了在动力电池工作荷电状态范围内的300周高倍率循环测试,并对循环前后电池正负极电位、储氢合金形貌、循环伏安特性的变化进行了研究.实验结果表明,高倍率充放电循环使电池性能下降的主要原因是负极合金性能的恶化.

| Abstract: | The effects of pulse charging and direct current charging technique on inner pressure and temperature of Ni-MH batteries were compared. Properties of motive batteries were investigated after 300 high-rate cycles in 30%- 80% SOC. The potential of positive, negative electrodes, appearance of hydrogen storage alloy, property of cyclic voltammetry curves before and after cycles were investigated. It proved that the main reason of lapse of Ni-MH batteries after high-rate cycles is the fading of negative electrode alloy performance. |
