摘要:

废旧锂离子电池的回收是近年来资源回收研究领域的热点,但相关回收体系的理论基础研究仍然较为薄弱。其中在热力学研究方面,研究者们大多仍以经典冶金物理化学理论为指导,并借助E-pH图、优势区域图等方法开展研究。本文对该领域已有的较为典型的热力学研究进行综述,详细阐述了热力学研究对废旧锂离子电池常规回收工艺的指导作用以及对三元正极废料选择性提锂、磷酸铁锂正极废料选择性提锂和失效电池材料再生修复等新技术开发的启发性作用。同时,基于对现有锂离子电池回收体系热力学研究的总结和评述,指出了未来锂离子电池回收体系热力学研究亟待解决的关键问题和发展方向。

Abstract:

Recycling of spent lithium ion batteries has become a hot topic in the field of resource recovery recently, but the theoretical basis of related recovery system is still comparatively weak. In the aspect of thermodynamics, most researchers still take the classical theory of metallurgical physical and chemical as the guide, and carry out research with the help of E-pH diagrams, predominance diagrams and other methods. In this paper, the existing typical thermodynamic studies in this field were reviewed. The guidance of thermodynamic research on the current recovery process of spent lithium ion batteries, the inspiration for the selective extraction of lithium from spent ternary cathode materials and lithium iron phosphate cathode materials, and the development of new technologies for the regeneration of failed battery materials were described in detail. Meanwhile, based on the summary and review of the existing research on the thermodynamics of lithium ion battery recycling system, the key problems to be solved and the direction for future thermodynamic research on lithium ion battery recycling were pointed out.

Key words: lithium ion battery, thermodynamics, recovery, regeneration
