摘要
通过对导电剂，添加剂，粘结剂的种类和用量以及浆料涂敷，干燥，成型等工艺参数的最佳确定，研制了体积比容量大于６３０ｍＡｈ／ｃｍ＾３以上的泡沫镍正极，并用其与自制负极组装成ＡＡ型ＭＨ／Ｎｉ电池，电池０．２Ｃ容量达１４５０￣１５２５ｍＡｂ，１Ｃ容量大于１３００ｍＡｈ且电池放电电压平台较高，０．２Ｃ放电１．２Ｖ以上时间占总时８５％左右。
The optimum composition and the preparation technology of the positive electrode of MH/Ni battery were studied in details. The specific capacity of the electrode made reached to 630 .mAh/cm3. The AA-sized MH/Ni battery made by such positive electrode with nickel foamed substrate had excellent performance, such as its capacity at 0. 2℃ rate achieved 1 450 ~ 1 525 mAh and at 1 C rate achieved more than 1 300mAh. and its discharge voltage platform was higher, the discharge time with output voltage above 1. 2V was about 85 % of the total time at 0. 2℃ rate.
