长寿命MH/Ni电池

采用改进循环寿命的LaNi5系储氢合金 ,高密度加锌氢氧化镍 ,氟化处理聚丙烯隔膜 ,同时采用带电热处理封口化成 ,制备了 1C充放电 ,10 0 %DOD ,循环寿命长达 80 0次以上的双发泡式氢镍电池。

Long Life MH/Ni Battery

A type of MH/Ni cells,which had more than 800 cycle lives when charged and discharged at 1 C rate current and 100%DOD was investigated.Foam nickel was used as current collector,a metal-hydrogen alloys of LaNi 5 with improved cycle life was used in negative electrode,positive was made as spherical nickel hydroxide of high bulk density and with the addition of zinc,and the cells'separator was polypropylene separator with F 2 treatment.After assembled,the cells were activated with precharge heat treatment.
