As attractive energy storage technologies, Lithium-ion batteries (LIBs) have been widely integrated in renewable resources and electric vehicles (EVs) due to their advantages such as high energy/power densities, high reliability and long service time. Although EVs basically do not produce pollution, the end-of-life (EOL) issues of LIBs cannot be ignored due to their potential economic benefits and environmental risks. Current methods for the retired batteries mainly include disposal, recycling and reuse. EV LIBs can be reused in a variety of applications with less demanding. Compared with recycling and disposal, reuse process can obtain better economic and environmental benefits. Many second life EV LIBs projects have been undertaken and demonstrated the great potential of reuse. However, the reuse should consider economic, environmental, technical, and various market perspectives. Technical challenges that must be faced include safety issues, assessment methods, screening and restructuring technologies, and comprehensive management during the reuse process. Economic feasibility issues, comprehensive supply chains, and the lack of relevant regulations also hinder large-scale development of reuse. It is foreseeable that improvements including standardization, big data and cloud-based technologies are desperately needed to maximize the industrialization of reuse and recycling.

作为有吸引力的储能技术，锂离子电池（LIB）由于具有高能量/功率密度，高可靠性和长使用寿命等优点，已广泛集成到可再生资源和电动汽车（EV）中。尽管电动汽车基本上不会产生污染，但由于其潜在的经济利益和环境风险，LIB的使用寿命（EOL）问题不容忽视。报废电池的当前方法主要包括处置，回收和再利用。EV LIB可以在要求不高的各种应用中重复使用。与回收和处置相比，再利用过程可以获得更好的经济和环境效益。已经进行了许多第二人生EV LIB项目，这些项目证明了重用的巨大潜力。但是，重用应考虑经济，环境，技术和各种市场观点。在重复使用过程中，必须面对的技术挑战包括安全问题，评估方法，筛选和重组技术以及全面管理。经济可行性问题，全面的供应链以及缺乏相关法规也阻碍了大规模的再利用发展。可以预见，迫切需要包括标准化，大数据和基于云的技术在内的改进，以最大程度地实现重用和回收的工业化。缺乏相关法规也阻碍了重复利用的大规模发展。可以预见，迫切需要包括标准化，大数据和基于云的技术在内的改进，以最大程度地实现重用和回收的工业化。缺乏相关法规也阻碍了重复利用的大规模发展。可以预见，迫切需要包括标准化，大数据和基于云的技术在内的改进，以最大程度地实现重用和回收的工业化。
