摘要
新能源车的发展是“双碳”达成的重要举措,三元锂离子电池作为新能源车重要动力源,其产销量逐年增加。随之退役三元锂离子电池产也会爆发式产生,退役三元锂离子电池回收利用具有资源、环境、经济等多重效益。为此,本文介绍近几年来退役三元锂离子电池资源化利用的研究进展,包括退役三元电池预处理和退役三元材料回收利用技术,其中,退役三元材料资源化利用包括火法冶金、湿法冶金、直接再生等方面,分析了各工艺优势与不足,并展望了退役三元材料资源化利用未来发展方向。
Developing new energy vehicles(NEV)is an important measure to achieve the goal of“Doub-le Carbon”.As the major power source of NEV,ternary lithium ion batteries have been increased by years in both production and sales,which leads to an explosive generation of used ternary lithium ion bat-teries.The recycle of used ternary lithium ion batteries has multiple benefits in terms of resource,envi-ronmental protection,economy and so on.In this paper,the research progress in recent years on the re-cycle of used ternary lithium ion batteries is introduced,including the pre-treatment and recycling tech-nologies of these batteries.The recycling technologies include pyrometallurgical process,hydrometallurgi-cal process,direct regeneration,etc.The merits and defects of these technologies are analyzed and the developmental direction of recycling spent ternary material is expected.
