摘　　要：应用SEM对阀控式密封铅酸蓄电池在循环过程中不同阶段的负极物质的微观结构进行了观察 ,发现有机膨胀剂的损失是导致负极活性物质出现不可逆硫酸盐化现象的主要原因。通过对负极物质配方的调整及充电方法的改进 ,能够有效地抑制负极硫酸盐化现象的出现。The micro structure of negative electrode materials of VRLA battery in different periods during cycing was researched by SEM.It was found that sulfation of the negative plate was caused mainly by the lose of the organic expander and the sulfation could be eliminated through the negative material formula and charge method adjustment.
