摘　　要：为回收利用废旧锂离子电池中的钴,以超声辅助低共熔溶剂浸出法提取钴。考察了浸出温度、时间、超声功率和固液比对钴浸出率的影响。结果表明:在浸出温度180℃、时间60 min、超声功率600 W和固液比1∶180(g∶m L,下同)的条件下,钴的浸出率可达99.99%。该方法不仅可实现钴的高效回收利用,还可避免其对环境的污染。To recover and utilize cobalt from spent lithium-ion batteries,cobalt was extracted by low eutectic solvent leaching assisted with ultrasound.The effects of leaching temperature,time,ultrasonic power,and solid-liquid ratio on cobalt leaching rate were investigated.The results showed that under the conditions of leaching temperature 180℃,time 60 min,ultrasonic power 600 W,and solid-liquid ratio 1∶180 (g∶m L),the leaching rate of cobalt reached 99.99%.This method can not only achieve efficient recovery and utilization of cobalt,but also avoid its pollution to the environment.
