摘　　要：提出了阀控铅蓄电池技术进步需解决的几个问题,即热失控、早期容量损失、水损失、负极板硫酸盐化、自放电率高、正极板腐蚀、负极汇流排腐蚀、循环容量衰退、吸附式玻璃纤维毡失效等;分别讨论了上述几个问题的现象、机理和解决方法。Some problems in the technical progresses of VRLA batteries, such as thermal runaway, primary capacity loss（PCL）, loss of water, sulfate in negative plate, high self-discharge rate, corrosion of positive plate and negative plate, decay of cycle capacity, invalidation of absorptive glass mat separator, were brought forward. And the phenomena, mechanism and solving methods were analyzed.
