废旧锂离子电池含有大量的钴、铜等紧缺有色金属元素和六氟磷酸锂等有毒有害物质,必须对其进行资源化回收及无害化处理.本文采用“拆解→NMP浸泡正极材料→钴酸锂粉末的浸出→P204萃取除杂→P507萃取分离钴、锂离子”流程处理废旧锂离子电池,获得了合格的氯化钴溶液.该工艺的特点在于:正极片中的铝箔以单质形态回收,而正极材料中97.33%的钴以氯化钴的形式回收,成功地实现了锂离子电池正极材料中有色金属的分离与回收利用.

Spent lithiumion secondary batteries contain amounts of scarce nonferrous metals as Co, Cu and toxic substance LiPF6, so the recovery of spent lithiumion secondary battery and innocent treatment are necessary and beneficial. In this paper, a recovery procedure of spent lithiumion secondary battery is proposed as follows:“splitting →pretreating the positive electrode material with NMP →leaching the cobalt in positive electrode material→ removing impurities extracted with P204 →separating cobalt ion from lithium ion extracted with P507”, obtaining qualified cobalt chloride solution. The characteristics of this process flow are:the aluminum foil in positive electrode material is recovered as simple substance, and the recovery rate of cobalt in the positive electrode material is 97.33% in form of cobalt chloride solution, which has a good effect on the separation and recovery of nonferrous metals in spent lithiumion secondary batteries positive electrode material.
