The large-scale retirement of electric vehicle traction batteries poses a huge challenge to environmental protection and resource recovery since the batteries are usually replaced well before their end of life. Direct disposal or material recycling of retired batteries does not achieve their maximum economic value. Thus, the second-life use of EV batteries has become the most economical and environmentally friendly solution. However, there are still many issues facing second-life batteries (SLBs). To better understand the current research status, this article reviews the research progress of second-life lithium-ion batteries for stationary energy storage applications, including battery aging mechanisms, repurposing, modeling, battery management, and optimal sizing. Energy management strategies are reviewed to maximize the economic benefits for SLBs, and the less-demanding applications of SLBs are presented. The technical challenges and future development trends of battery reusing technologies are also discussed. Finally, the conclusions and relevant recommendations for future studies are summarized.

用于固定储能应用的二次锂离子电池回顾

电动汽车牵引电池的大规模报废对环境保护和资源回收提出了巨大挑战,因为电池通常在使用寿命结束前就被更换。退役电池的直接处置或材料回收并不能实现其最大的经济价值。因此,电动汽车电池的二次使用成为最经济、最环保的解决方案。然而,二次电池(SLB)仍然面临许多问题。为了更好地了解当前的研究现状,本文回顾了用于固定储能应用的二次锂离子电池的研究进展,包括电池老化机制、再利用、建模、电池管理和优化尺寸。回顾了能源管理策略以最大限度地提高 SLB 的经济效益,并介绍了 SLB 要求不高的应用。还讨论了电池再利用技术的技术挑战和未来发展趋势。最后,总结了结论和对未来研究的相关建议。
