【摘要】 介绍了MH-Ni蓄电池在常温条件下不同储存期的性能试验。试验结果说明:MH-Ni蓄电池长期储存后,容量发生不可逆衰减是由于正极中的CoO OH在长期处于低电压下的分解造成的;报导了解决MH-Ni蓄电池长期储存后容量衰减及性能下降的有效方法是控制储存电池的开路电压不低于1.0V。更多还原

【Abstract】 The performance test of Ni-MH batteries stored at normal temperature for several months was introduced in this paper.The experimental results showed that the capacity fading of Ni-MH batteries stored at normal temperature for several months was caused by the decomposition of CoOOH in positive electrode at low voltage.The method to resolve this problem was described.The open-circuit voltage of this storage battery must be controlled not to be below 1.0 volt.更多还原
