| 摘 要： | 废旧锂离子电池中钴的含量较高．钴具有较强的毒性,且资源稀少．为此,研究了废旧锂离子电池的湿法回收工艺过程,并分析了废旧锂离子电池中钴和锂在硫酸溶液中的漫取过程动力学．采用了解体电池塑料外壳、钢壳、正负极材料、N-甲基吡咯烷酮(NMP)分离铝箔与正极活性材料以及硫酸浸取钴与锂的回收工艺．结果表明,铝片的回收率接近100％,钴和锂的浸取率均超过99．6％,同时分析了漫取过程中的工艺参数对钴和锂的漫取率的影响．

| Abstract: | The wet-chemical recovery process of spent lithium ion batteries was investigated.The leaching process kinetics of Co and Li of spent lithium ion batteries with sulfuric acid was analyzed.An effective process for recovering cobalt and lithium was determined,including disassembling batteries plastic crust,steel crust, cathode and anode materials,separating aluminum and anode active materials using liquid NMP,and sulfuric acid dissolution of the slag.The results show that the recovery rate of aluminum reaches nearly 100%,and the leaching rates of cobalt and lithium are more than 99.6%.The effects of the processing parameters,such as the temperature,the sulfuric acid concentration,the H_2 O_2 addition,the ratio of liquid to solid in the solution,and reaction time on the leaching rates of cobalt and lithium in the leaching process were investigated. |
