摘　　要：详细探讨了MH／Ni电池化成的若干基本原理：（1）钴在化成中的作用，设计电池的负、正极容量比应考虑放电预留量、充电预留量；（2）正负极化成机理，并指出了提高正负极化成效果的可能途径；（3）分析了电池微短路的原因，并指出了解决方案；（4）放电平台特性比容量特性能更充分地评价化成效果;(5)详细比较了封口、开口化成的异同点，并探讨了封口化成优于开口化成的原因。The mechanism of sealed formation for MH/Ni batteries was discussed in detail: (1)The role of cobalt in sealed formation, to design the ratio of the eapacity of negative to that of positive discharge and charge reserve should be considered. (2)The mechanism of formation of positive and negative and the possible access to improve the formation effect of the two electrices was pointed out. (3 ) The analysis of the reason of micro-short circuiting of the batteries, the resolution was presented. (4 )The formation effect could be evaluated fully with discharge plateau with capacity characteristics. (5) The sealed formation was compared in detail with the opened formation and the reason that the sealed formation was better than the opened formation was discussed.
