| 摘 要： | 综述了镍基电池回收再生的方法，并分析了目前镍基电池常用的火法、湿法回收以及再生技术的利弊，提出了一种锌镍电池回收再生思路，并对该思路中负极回收方法进行了探究.结果表明，该锌镍电池回收再生思路具备一定可行性，且该思路下负极回收效果良好；采用硝酸浸出可使废阴极中Zn和Cu的浸出率分别达到99.94%和99.99%；采用锌粉置换和萃取法均可使浸出液净化过程中杂质铜的去除率达99%以上.

| Abstract: | The recovery and regeneration methods of nickel-based batteries were summarized, and the advantages and disadvantages of pyrogenic, wet recovery and regeneration technologies commonly used in nickel-based batteries at present were analyzed. A recovery and regeneration idea of zinc-nickel batteries was proposed, and the negative electrode recovery method in this idea was explored. The results show that the idea of recovering and regenerating zinc-nickel battery is feasible, and the negative electrode recovery effect is good under this idea. The leaching rate of Zn and Cu in waste cathode can reach 99.94% and 99.99% respectively by nitric acid leaching. The removal rate of impurity copper in leaching solution purification process can reach more than 99% by zinc powder replacement and extraction. |
