摘要
按火法冶金法和湿法冶金法对便携式锂离子电池回收再利用技术进行分类总结,其中湿法冶金技术回收率高,得到了广泛应用。湿法冶金回收过程包括电池前处理、材料溶解、元素回收或材料再生等几个步骤,元素回收是湿法冶金技术中应用最广的资源再利用方式,主要回收方法有沉淀法、电化学法、离子交换法、萃取法、盐析法等。大容量锂离子电池的回收再利用尚无成熟技术,对其中存在的安全性和经济性问题进行了分析。根据锂离子电池行业的可持续发展要求,大容量锂离子电池的回收再利用技术研究需要引起重视。
Recovery methods of portable lithium-ion batteries were summarized by pyrometallurgy and hydrometal- lurgy. The most widely used is the hydrometallurgical methods with high recovery ratio. The processes of battery pretreatment, materials dissolution and resource utilization constitute hydrometallurgical methods. The resource utilization techniques include two technologies, namely elements recovery and materials regeneration. The technology of elements recovery including precipitation method, electrochemistry method, ion exchange method, extraction method and salt out method is widely used. However, there are still no mature recovery techniques of high-capacity lithium-ion batteries. The security and economy problems in recovery of lithium-ion batteries were studied. According to the continued development of U-ion batteries, the research of recovery techniques for high-capacity lithium-ion batteries should be taken seriously.
