摘要： 对Ni-MH电池正负极片修饰技术进行了研究。结果表明：该方法可增强电极的导电性，降低电池的内阻，提高电池的充放电效率和大电流放电能力，改善了电极的电化学性能。利用极片修饰技术制备的高功率D型Ni-MH的比功率和循环寿命均有提高。在电解液中，添加微量添加剂nT明显降低电池充电后期的内压，提高电池的充电功率和循环寿命。

Abstract: The electrodes surface modified technology of Ni-MH batteries are studied. The experiment results demonstrate that this method could remarkably improve the conductivity of the electrodes. The new process improves the characteristics of the Ni-MH batteries, especially concerning the battery capacity and discharge capacity at high rates. The high power battery is developed. It has long cycle life. The inner pressure test shows that battery with additives displays a much lower inner gas pressure on charging, the performance of high power on charging and the longer cycle life.

Key words: Additives, High power, Ni-MH Batteries, Surface modification
