摘要

为了应对迫在眉睫的气候变化问题和实现可持续发展目标，镍钴锰锂(1-x-y)二氧化物（NCM）电池因其优势而受到电动汽车的青睐，但其大规模生产带来了回收方面的挑战。鉴于 NCM 正极材料中关键金属含量高，废 NCM 电池的回收潜力巨大。然而，现有的回收方法无法为工业回收应用提供理论指导。近期的研究重点是新型绿色回收方法，以弥补这些不足。本综述评估了当前 NCM 正极材料的回收方法，包括关键金属的回收、正极材料的再生及其再利用，同时讨论了预处理技术的最新进展。目的是加深理解并促进开发更好的回收解决方案，为电池回收的产业化提供理论基础和技术支持。

Recycling, regeneration, and reutilization of cathode materials of spent LiNixCoyMn(1-x-y)O2 batteries

In response to the imminent issue of climate change and in order to achieve the Sustainable Development Goals, LiNi_xCo_yMn_(1-x-y)O₂ (NCM) batteries are favored in electric vehicles due to their advantages, but their large-scale production presents recycling challenges. Given the high content of critical metals in NCM cathode materials, the recycling potential of spent NCM batteries is significant. However, existing recycling methods fall short in providing theoretical guidance for industrial recycling applications. Recent research has focused on novel and green recycling methods to address these gaps. This review evaluates current recycling methods for NCM cathode materials, including the recovery of critical metals, regeneration of cathode materials, and their reutilization, while discussing recent advancements in pretreatment techniques. The aim is to enhance understanding and stimulate the development of better recycling solutions, providing theoretical foundations and technical support for the industrialization of battery recycling.
