摘要
AB2 型储氢合金的活化方法有多种 ,主要有添加微量稀土元素法、氟化处理、热碱充电、热碱浸泡和球磨法等 ,其目的是通过改善合金微粒表面状态来实现电极的高反应性能和快速活化能力。通过比较 ,认为表面处理是比较理想的活化方法 ,并提出单纯采用KOH溶液处理的方法。
There are some methods to activate the AB 2 hydrogen storage alloys:method of adding trace thulium,method of F_treatment,hot alkali charging treatment,hot alkali dipping treatment and ball milling.Because of improving the surface state of alloy particles the high reaction property and quick activation of electrode can be realized.By comparison,surface treatment is considered as the perferable method,meanwhile,the new method only using KOH solution is proposed.
