Abstract

Abstract:

Lithium-ion batteries (LIBs) has been extensively used in electronics, electric vehicles (EVs), and energy storage. As the rapid development of EVs, the consumption of LIBs will substantially increase. Accordingly, large numbers of spent LIBs will be generated. Improper disposal of spent LIBs will not only result in long-term environmental impact, but also is a major waste of resources. Therefore, the recovery of these wastes is quite important, especially for achieving the Li resource supply and demand balance. State-of-the-art techniques for the recovery of valuable metals from spent LIBs were reviewed, and the future direction of the recovery technique was also discussed in this study. The research in the future should be focused on the technology and equipment of the safe and efficient dismantling, the integrated recovery technology of valuable elements, the resynthesis process of electrode materials, and the avoidance of secondary pollution.

Key words: spent lithium-ion batteries, secondary resources, recovery, regeneration, leaching

摘要：

锂离子电池被广泛应用于电子产品、电动汽车和大规模储能材料等多个领域。随着电动车市场的快速发展，其使用量还将显著增加，随之产生数量极大的退役锂离子电池。退役锂离子电池的回收利用可以避免环境污染和资源浪费，尤其对实现锂资源供需平衡具有重要意义。综述了退役锂离子电池中有价金属元素回收技术研究现状，探讨了该领域未来发展方向。电池安全高效拆解技术与装备、有价元素整体化回收技术、电极材料再制备工艺以及避免二次污染环境是未来退役锂离子电池循环利用领域值得关注的重点。
