【摘要】 随着电动车及储能系统的快速发展，磷酸铁锂（LiFePO₄,LFP）电池凭借其卓越的安全性、稳定性及较长的循环寿命而被广泛应用。然而，随着使用时间的延长，LFP电池在实际使用中逐渐暴露出失效问题，这些问题不仅影响了电池的性能，也为电池的回收与再利用带来了新的挑战。现有的LFP电池再生流程包括修复前预处理和化学法再生，其中预处理包括放电、拆解与分选等，化学法再生包括固相修复、液相回收和直接再生，在废水处理、热能消耗、回收流程、环保和进步空间方面上固相法和液相法各有优势。综述旨在对退役的磷酸铁锂电池的回收修复领域总结，阐述预处理中的物理分选原理，对常见的回收与修复方法和经济效益进行评估，为未来的回收产业提供依据。未来的研究应侧重于进一步探索工艺优化，回收与修复技术的开发应探索更高效、低成本的工艺，LFP电池的再生行业将展现广阔的应用前景，推动电池产业的可持续发展。更多还原

【Abstract】 With the rapid development of electric vehicles and energy storage systems, lithium iron phosphate（LiFePO₄, LFP） batteries are widely used due to their excellent safety, stability, and long cycle life. However, with the extension of usage time, LFP batteries have gradually exposed failure problems in actual use, which not only affect the performance of the battery, but also bring new challenges to the recycling and reuse of the battery. The existing LFP battery regeneration technology can be roughly divided into echelon use, pre-treatment, and chemical regeneration. Pre-treatment includes discharge, disassembly and physical separation, while chemical regeneration includes solid-phase repair, liquid-phase recovery, and direct regeneration. Solid phase and liquid-phase methods have their own advantages in wastewater treatment, thermal energy consumption, recovery process, environmental protection, and progress space. This review aims to summarize the field of recycling and repair of retired lithium iron phosphate batteries, summarize the assessment methods of batteries state of health（SOH） in cascade utilization, explain the physical sorting principles in pretreatment, evaluate common recycling and repair methods and economic benefits, and provide a basis for the future recycling industry. Future research should focus on further exploring process optimization, and the development of recycling and repair technologies should explore more efficient and low-cost recycling processes. With the continuous progress of technology and the increase in market demand, the recycling and reuse of LFP batteries show broad application prospects, promoting the sustainable development of the battery industry.更多还原
