摘　　要：随着新能源汽车的行业发展,三元锂离子电池因其能量密度等优势被广泛应用。锂离子电池含有有机溶剂等有害物质及重金属,当动力电池达到退役年限,如果不对其进行有效处理,会对环境和生物造成一定的危害,且三元电池中富含Co、Ni、Li等战略资源,因此,回收动力电池中的三元电池具有重大的经济价值和环保意义。文章总结了现有资源再生技术的研究进展并分析了各技术的优缺点,指出碱浸出将会是未来绿色资源再生的技术方向之一。With the industry development of new energy vehicles,ternary lithium-ion batteries are widely used because of their energy density and other advantages.Lithium-ion batteries contain organic solvents and other hazardous substances and heavy metals,when the power battery reaches the retirement age,if it is not dealt with effectively,it will cause some harm to the environment and biology,and ternary batteries are rich in strategic resources such as Co,Ni,Li,so the recovery of ternary batteries in power batteries has a significant economic value and environmental significance.This paper summarizes the research progress of the existing resource regeneration technology and analyzes the advantages and disadvantages of each technology,and points out that alkaline leaching will be one of the technical directions of green resource regeneration in the future.
