发明名称 Verfahren zur Herstellung einer sekundären alkalischen Batterie
摘要 An alkaline secondary battery comprising a negative electrode comprising cadmium, zinc or iron or an oxide or hydroxide thereof or a hydrogen absorbing alloy, a positive electrode comprising a metal oxide or a metal hydroxide, and a separator, which are all impregnated with an electrolyte comprising an alkaline aqueous solution is disclosed, wherein the separator is made of a polyolefin fiber sheet which has a wicking rate of pure water of at least 10 mm per 2 minutes when one end of the sheet is dipped in pure water at 20 DEG C and 60% RH. Since the separator is chemically stable and exhibits sufficient hydrophilic properties, the battery retains a high electrode utilization even at a high rate discharging and has a practically sufficient cycle life. <IMAGE>
