阀控式密封铅酸蓄电池现状及待解决的技术

Current States and Solutions to Problems in VRLA

概述了阀控密封铅酸蓄电池在各应用领域中的现状及存在的问题。在ＳＬＩ蓄电池中ＶＲＬＡ 处于试验阶段，需要解决在高温条件下，负极膨胀剂的稳定性，以及失水和热失控问题。ＶＲＬＡ 在固定型电池中应用是成熟的，但在工作过程中要求监控。做为动力ＶＲＬＡ 是比较困难的，遇到了使用寿命与比能量之间的矛盾，以及正极活性物质的降解。把阀控密封电池用于与风能、太阳能配套，目前还属空白。小容量的、便携式ＶＲＬＡ 有着广泛的应用前景，有大量的新品种需要开发。

This is to state the current status and solutions to problems in VRLA.Nowadays in SLI battery VRLA is just on test.We need solve the instability of negative plate expanders,as well as water loss and thermal run away.To make VRLA motive power is difficult because of degradation of positive active material and the contradiction between service life and specific energy.VRLA in stationary battery is ripe,although it needs supervision during operation.The VRLA has not been applied to sun-power and wind power gen...
