Abstract

Lithium-ion batteries (LIBs) are widely used in the mobile electronics, power, energy storage and other fields due to their excellent electrochemical performance, but their limited service life has resulted in a large number of spent LIBs being discarded. Due to the advantages of high recovery efficiency and mild reaction conditions, the combined pyro-hydrometallurgical process for recovering valuable metal elements from spent LIBs is emerging in line with the principles of green chemistry and has potential for large-scale industrial applications. Here we review current developments in the combined recovery process, aiming to figure out the challenges and future directions for the combined process. In detail, thermal pretreatment methods for collecting the cathode material from spent LIBs, the combined recovery process for treating the cathode material, and the subsequent separation and extraction process are summarized. Furthermore, the practical application of combined recycling schemes is demonstrated. Finally, the development and challenges of the combined process in recycling spent LIBs are revealed. Achieving pollution-free emissions and high-value utilization of spent LIB resources with low-cost treatment are future directions for the combined process.

从废锂离子电池中回收有价金属元素的高温-湿法联合冶金技术研究进展

锂离子电池因其优异的电化学性能被广泛应用于移动电子、电力、储能等领域，但由于其使用寿命有限，导致大量废旧锂离子电池被丢弃。从废lib中回收有价金属元素的热法-湿法联合冶金工艺具有回收效率高、反应条件温和等优点，符合绿色化学原理，具有大规模工业应用的潜力。本文综述了目前联合采油工艺的发展现状，旨在找出联合采油工艺面临的挑战和未来的发展方向。详细介绍了从废lib中回收正极材料的热预处理方法、处理正极材料的联合回收工艺以及后续的分离提取工艺。此外，还说明了组合回收方案的实际应用。最后，介绍了废lib联合回收技术的发展和面临的挑战。以低成本处理实现废LIB资源的无公害排放和高价值利用是未来联合工艺的发展方向。

期刊介绍： Green Chemistry is a journal that provides a unique forum for the publication of innovative research on the development of alternative green and sustainable technologies. The scope of Green Chemistry is based on the definition proposed by Anastas and Warner (Green Chemistry: Theory and Practice, P T Anastas and J C Warner, Oxford University Press, Oxford, 1998), which defines green chemistry as the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Green Chemistry aims to reduce the environmental impact of the chemical enterprise by developing a technology base that is inherently non-toxic to living things and the environment. The journal welcomes submissions on all aspects of research relating to this endeavor and publishes original and significant cutting-edge research that is likely to be of wide general appeal. For a work to be published, it must present a significant advance in green chemistry, including a comparison with existing methods and a demonstration of advantages over those methods.
