摘要
采用孔率测试、X射线衍射、电镜扫描等手段 ,对循环失效后的活性物质 (AM )的成分与结构进行了较深入的研究 ,分析认为循环使用条件下 ,电池的失效主要是由正极活性物质(PAM )的软化。
The components and structure of failed active material(AM)after cycling were investigated using porosity test,XRD and SEM.It is showed that the failure mode of VRLA batteries is caused by PAM softening and shedding under the cycling operation condition.
