有机添加剂对密封铅酸蓄电池电性能的影响

Effect of organic additives on the performance of sealed lead-acid batteries

采用国产1号微孔玻璃纤维膜制做的6V4Ah密封铅酸蓄电池,由于该膜内存在着较多的有害杂质(如Cu、Fe),导致了比较严重的自放电.有机添加剂茴香醛(An)及引杜林(In)对上述电池的自放电有抑制作用,并可改善对密封铅酸蓄电池的电性能.

It is revealed that the sealed lead-acid batteries made with 'Domestic No. 1' glass-micro fibre separator have serious self-discharge resulting from the impurity materials, such as Fe, Cu etc, in the separator. The inhibition effect of organic additives anisaldehyde(An) and indulin (In) on self-discharge as well as the positive effect on discharge performance are presented.
