摘　　要：废旧锂离子电池中含有大量的有价金属Co、Li、Mn等。回收废旧锂离子中的有价金属,不仅可以降低废旧锂离子可能产生的污染,还可以提高废旧锂离子电池的利用率。本文对超声波强化浸出废旧锂离子电池中的钴进行了研究。探讨了浸出时间、柠檬酸浓度、还原剂用量、固液比、超声波功率对浸出率的影响。实验表明,采用超声波强化浸出技术可以有效地促进柠檬酸、双氧水对废旧锂离子电池中钴的浸出。The cathode material in the waste lithium-ion batteries contain a large amount of valuable metals such as Co, Li, Mn. Recycling valuable metals from waste lithium-ion batteries can reduce the pollution caused by the waste lithium-ion batteries and improve the utilization rate of the waste lithium-ion batteries In this paper, Ultrasonic enhanced leaching of cobalt from waste lithium-ion battery was studied. The leaching parameters such as effects of ultrasonic time, citric acid concentration, H2 O2 concentration, ratio of solid to liquid,ultrasonic power, have been analyzed and compared on the leaching rate. The result indicates that the leaching of cobalt from waste lithium-ion battery with citric acid and hydrogen peroxide can be effectively promoted by ultrasonic enhanced leaching technology.
