The rapid development of the electric vehicle industry has spurred the prosperity of the lithium ion battery market, but the subsequent huge number of spent lithium ion batteries (SLIBs) may bring severe environmental problems. Because of the advantages of low raw material requirements and little waste liquid production, pyrometallurgical technology is suitable for recycling SLIBs in large-scale industrial applications. After decades of research, the practice of pyrometallurgical technology in related fields has developed a lot. There are three essential components of SLIBs, namely, binders and electrolytes, cathode, and anode. This article summarizes the development of pyrometallurgical technologies in dealing with these three parts and analyzes the strengths as well as weaknesses of each technology. Moreover, it reveals the evolution and the challenges of pyrometallurgical technology in recycling SLIBs. A high-value utilization with the characteristics of an overall resource utilization of waste batteries is a promising development direction for pyrometallurgical technology.

废旧锂离子电池回收中的火法冶金技术：发展与挑战

电动汽车行业的快速发展刺激了锂离子电池市场的繁荣，但随之而来的大量废旧锂离子电池（SLIB）可能带来严峻的环境问题。由于具有原料要求低、废液产生量少等优点，火法冶金技术适合于大规模工业应用中回收SLIB。经过几十年的研究，火法冶金技术在相关领域的实践有了很大的发展。SLIBs 具有三个基本组成部分，即粘合剂和电解质、正极和负极。本文针对这三个部分总结了火法冶金技术的发展，并分析了每种技术的优缺点。而且，它揭示了火法冶金技术在回收 SLIB 方面的演变和挑战。具有废旧电池资源综合利用特点的高价值化利用是火法冶金技术的一个有前景的发展方向。
