空间用Cd-Ni与H_2-Ni电池的比较

Comparison of nickel cadmium and nickel hydrogen cells for space use

比较了Ｃｄ－Ｎｉ与Ｈ２ －Ｎｉ电池的特性，分析了它们的容量限制特性、记忆效应、失效模式和寿命影响因素。对正限制、负限制Ｈ２－Ｎｉ电池进行了对比试验，负限制电池具有初容量高、充电终止压力低和反极电压高等特性。泡沫镍电极、毡电极和镍纤维电极的研究和应用将提高Ｃｄ－Ｎｉ与Ｈ２

Characteristics of nickel cadmium and nickel hydrogen cells were compared. Meanwhile, their capacity limited performance, memory effect, failure mode and factors affecting lifetime were analyzed. The contrast test between positive and negative limited cells was made. The results show that compared with positive limited cell, negative limited cell possesses higher initial capacity, lower EOC pressure and higher reversal voltage. The research and application of new lightweight foam, felt and fiber nickel electrodes technologies can increase specific energy and cycle lifetime of Ni Cd and Ni H 2 cells.
