摘　　要：利用化学模式识别方法对不同电极制备工艺条件的MH Ni电池的放电容量和循环寿命进行了分析 ,并得出了提高电池相应性能的判据。对于放电容量 ,粘结剂和导电剂均为影响的主要因素 ,两者的作用为互相牵制 ,其中粘结剂为最主要影响因子 ;对循环寿命的影响添加剂上升为最主要的因素 ,粘结剂和导电剂之间的作用仍为互相牵制。适当地减小添加剂和导电剂的比例、提高粘结剂的粘结强度对提高电池的综合性能有好处。The discharge capacities and cycle life of Ni-MH batteries with different technology factors were analyzed by chemical pattern recognition method, and criteria for improving battery properties were obtained. The results show that binder, conductive and additive are important factors for battery properites. Besides, binder and conductive act on discharge capaicities and cycle life in opposition to each other, and binder and additive are the most important factors. Reducing the ratio of additive and conductive and increasing the strengtheness of binder are favorable for improving synthetical properties of battery.
