铅蓄电池负极膨胀剂的作用及筛选方法

Effect and Selection of Negative-Plate Expanders of Lead-acid Battery

目前铅蓄电池工业生产中常用的负极膨胀剂主要有炭黑、硫酸钡和有机膨胀剂。文章概述了膨胀剂对负极的影响及其各自的作用机理，着重讨论了有机膨胀剂的作用机理。循环伏安技术可以有效地筛选负极膨胀剂。初步研究表明，某种合成的负极膨胀剂可以明显地提高铝蓄电池的负极性能。

At present, carbon black, barium sulfate and oreanic expanders are used as negative-plate expanders in the industries of lead-acid batteries. In this paper, the effects of expanders on the negative plate and mechanisms by which expanders play their roles are surveyed. Stress is placed on discussing the mechanisms of organic expanders.The eyelic voltammetry can he effectively applied to selecting efficient negative plate expanders. A prelihanary study showed that a cedrin kind of synthetic expanders could significandy enhance the performance of negative plates of lead-acid battenes.
