在SC型高功率镍氢电池的负极中添加不同含量的碳纳米管制备SC型高功率镍氢电池,并对其容量、大电流放电性能和循环寿命进行研究.结果发现,碳纳米管的加入有利于提高电池的综合性能,尤其是大电流放电性能和循环寿命;加入碳纳米管的含量为0.8%（w）时电池的综合性能最好,其最高容量达到3369mAh,2C（6000mA）循环600次后容量仍然保持在3280mAh（97%DOD（放电深度））以上,5C（15000mA）循环180次容量仍然有2850mAh（89.1%DOD）以上.

英文摘要：

The carbon nanotubes were added to the cathode to prepare SC high-power Ni/MH batteries. The capacity, large-current discharging performance and cycle life were investigated. It was found that adding carbon nanotubes was greatly advantageous to enhance the batteries＇ overall performance, especially the large-rate discharge performance and cycle life. When the weight ratio of the MWNTs in the compound electrode was 0.8%（w）, the overall performance of the battery was the best, which showed a highest capacity of 3369 mAh in the condition of 3000 mA charge current and 6000 mA discharge current （2C-rate discharge）, and the cycle life surpassed 600 times, the capacities passed 3280 mAh （97%DOD （depth of discharge））. Especially in the condition of 5C-rate large-current discharge （3000 mAh charge current and 15000 mA discharge current）, its cycle life surpassed 180 times （89.1%DOD）.
