中文摘要：
首次采用超声波震荡的方法，利用其特有的“空化效应”，使电池在非破坏状态下在一定程度上可达到电池容量再生的目的，部分实现了MH—Ni电池的循环再利用。利用SEM、XRD、EDAX等检测方法对经超声波作用前后的材料形貌及表面元素变化做了进一步的分析与讨论。实验结果表明，MH—Ni电池在一定介质温度下经超声波处理后，正、负极材料活性物质均有较为明显的分散现象，可使负极表面的惰性氧化层分散脱落，露出新鲜表面，增加参加反应的活性中心，改善电板的电催化活性。超声波作用6h后的电池电化学性能的恢复最为明显。
英文摘要：
Ultrasonic treatment was first used to recycle MH-Ni batteries in this paper. The effects of ultrasonic treatment on electrode material performance of MH/Ni batteries have been investigated by using SEM and XRD methods. The results indicated that there are obvious disperse phenomena in the positive and negative electrodes along with the ultrasonic treatment. This can make the inertia oxidation layer break off from the negative electrode, and the fresh surface was come out. These changes can increase the active materials center of the reaction, as well as improve the catalyses capability and discharge ability. The improvement of electrochemical performance for MH-Ni batteries is furthest evidence bv ultrasonic treatment for 6h continuously.
