| 摘 要： | 考察了在成型正极表面分别浸聚四氟乙烯（PTFE）和羧甲基纤维素（CMC）对MH-Ni电池自放电性能的影响。实验结果表明,CMC处理能明显降低镍电极的自放电率,但不能改善电池的自放电性能;相反,PTFE处理虽不能降低镍电极自放电率,但却能明显改善电池的自放电性能。MH-Ni电池的自放电性能可能与负极析出的H2在正极上的电化学氧化过程密切相关。

| Abstract: | The surface of the formed positive electrodes of Ni-MH batteries were modified separately with polytetrafluoroethylene (PTFE) and carboxymethyl cellulose (CMC) and the self -discharge performance of the batteries were studied. The results showed that after CMC modification, the self-discharge rate of the nickel electrodes was significantly reduced, but the batteries' self-discharge rate had little change. On the other hand, after PTFE modification, the self -discharge rate of the nickel electrodes was not l... |
