废旧锂离子动力电池的性能和梯次利用的可能性研究

Possibility Research of Performance and Cascade Utilization for Used Lithium-Ion Power Batteries

近年来随着电动汽车产业的发展,大量锂离子动力电池达到使用寿命,进入报废退役阶段,报废动力电池的处置成为人们关注的热点。综述了废旧锂离子动力电池的性能和梯次利用方面的技术进展,指出做好筛选分类与重新组合的工作,以确保二次利用电池组内部电池单元性能的同质性将是梯次利用的关键。

In recent years, with the development of the electric vehicle industry, a large number of lithium-ion power batteries have reached the end of their service life and entered the stage of scrapping and decommissioning. The treatment and disposal of discarded power batteries has become a hot spot of attention. This article reviews the technical progress of the performance and echelon utilization of used lithium-ion power batteries, and points out that doing a good job of screening, classification and recombination to ensure the homogeneity of the internal battery cell performance of the secondary battery pack may be the key to echelon utilization.
