摘　　要：在负极活性物质中加入能改善负极内活性物质电子传递的RH (离子交换型有机物 )和具有凝聚、交联作用的聚四氟乙烯 (PTFE)乳液 ,与普通负极添加剂作比较 ,探讨能改善铅蓄电池负极的添加剂。对 6种含有不同添加剂和组成的蓄电池负极 ,就电池充电接受能力、恒流放电特性、电极循环寿命、RH的含量及RH与PTFE联用等方面进行了试验。结果表明 ,与普通添加剂比较 ,加有RH的电池 ,其电池充电接受能力和恒流放电特性有所提高 ,但其电极循环寿命却较短 ,当与PTFE联用时 ,能改善RH易脱落的缺点 ,延长电极循环寿命 ;说明曾用作正极添加剂的RH作为负极添加剂使用时 ,负极的充电接受能力和放电性能得到改善 ,与PTFE联用 ,其寿命得以延长。In order to sutdy the additives for improving the negative electrode of lead-acid battery, an additive RH (ion exchange organic substance) which would increase the electrons transmission in the active material of negative electrode and polytetrafluoroethylene (PTFE) colloid were added into the negative plate. Six negative electrodes with different actives were studied by charge acceptance test, constant-current discharge test, cycle life test, RH content test and RH-PTFE cooperating utilization test. The experiment results show that charge acceptance and constant-current discharge characteristics of the battery with RH are improved, but its cycle life is shorter than the ordinary electrode. While RH is added into the negavtive electrode cooperated with PTFE, the charge discharge characteristics and cycle life of the battery are more effectively improved.
