摘要
测试胶体蓄电池10小时率100%DOD、50%DOD和15分钟恒功率的循环性能。对循环失效电池解剖分析,认为电池失效的主要原因是正极活性物质软化,但三种循环模式下软化的位置有所不同。
The cycle performances of gelled lead-acid batteries with 10 h rate of 100%DOD,50%DOD and 15 min constant power were tested.The main reason for the failure of the battery is the softening of positive active materials,but the softening positions of the three cyclic modes are different.
