近年来以贮氢合金材料作负极，氧化镍、二氧化锰等物质作正极的电池发展很快，尤其是金属氢化物／镍蓄电池（简称ＭＨ／Ｎｉ电池），已被作为一种新型的“绿色能源”而广泛研究￣［１，２］。美国、日本、法国及我国都竞相开发。ＭＨ／Ｎｉ电池虽有许多优点，但也存在一些亟待解决的问题。如随着电池循环次数的增加，负极容量逐渐下降，以致电池寿命终止。有关研究认为：这是由于贮氢合金被氧化￣［３］和粉化的结果，本文主要研究电池中贮氢合金在各种条件下被氧化的规律。 In recent years, hydrogen storage alloy materials for the anode, nickel oxide, manganese dioxide and other substances as the cathode of the rapid development of the battery, especially the metal hydride / nickel batteries (referred to as MH / Ni battery), has been used as a new type of “ Green energy ”and extensive research [1,2]. The United States, Japan, France and China are racing to develop. Although there are many advantages of MH / Ni battery, but there are some problems to be solved. As the number of battery cycles increases, the capacity of the negative electrode gradually decreases, resulting in the end of battery life. The study shows that: This is due to the hydrogen storage alloy is oxidized ~ [3] and the results of the chalking, the main study of the battery hydrogen storage alloy oxidation in a variety of conditions.
