摘要:
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.
Abstract:
Spent lithiumion secondary batteries contain amounts of scarce nonferrous metals as Co, Cu and toxic substance LiPF6, so the recovery of spent lithiumion secondary battery and innocent treatment are necessary and beneficial. In this paper, a recovery procedure of spent lithiumion 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 nonferrous metals in spent lithiumion secondary batteries positive electrode material.
