镍氢电池自从1985年开始正式投入开发工作,工作电压为12Ｖ的电池可与镍镉电池互换,而且具有相当于后者15倍以上的电容量,是90年代后期投入市场的。作为镍氢电池负极材料的贮氢合金,当初使用了ＡＢ5型稀土镍系合金,近年来作为稀土元素采用了廉价的混合稀土(Ｍｍ)并且通过利...
Nickel-metal hydride batteries have been put into development since 1985, and the batteries with operating voltage of 12V can be exchanged with nickel-cadmium batteries and have the capacity equivalent to more than 15 times that of the latter. It was put on the market in the late 1990s. Nickel-hydrogen battery as a negative electrode material hydrogen storage alloy, originally used AB5-type rare earth nickel alloy, rare earth elements in recent years as a cheap mixed rare earth (Mm) and through the ...
