摘要/Abstract

摘要：

近些年，随着新能源产业蓬勃发展，动力电池也将迎来大规模退役潮。动力电池的梯次利用不仅可以充分发挥电池价值降低电池成本，同时也能削弱退役动力电池对土壤和环境造成的威胁，缓解传统储能系统成本高、收益低等问题。目前，传统分容定容一致性的筛选技术效率低、成本高，难以适应多场景的梯次利用动力电池一致性的筛选需求，数据分析在筛选过程中没有发挥必要的作用，快速高效的电池筛选技术成为退役电池规模化应用的关键技术之一。此外，现有梯次利用技术无法解决一致性差等问题，重组电池梯次运行衰减较快，且老化规律难以预判，存在较大的安全隐患，退役动力电池梯次利用在一致性管理、动态安全监测及调控等技术在规模化应用中仍需实现突破。虽然梯次利用电池储能系统示范应用已初具成效，但仍面临系统高安全性和经济性等技术难题。本文通过对近期相关文献的探讨，综述了退役动力电池的分选、评估、筛选、检测、重组、均衡以及安全等关键技术的研究现状，并对退役动力电池梯次利用相关的产业政策以及国家行业标准进行梳理，有望为退役动力电池大规模梯次利用提供参考。

Abstract:

With the vigorous development of the new energy industry in recent years, power batteries will usher in a large-scale retirement tide. Echelon utilization of power batteries can not only maximize the value of batteries and reduce the life cycle cost of power batteries but also weaken the threat of retired power batteries to the environment and alleviate the problems of high cost and low income associated with traditional energy storage systems. The traditional screening technology for consistency in the capacity division and constant capacity has low efficiency and high cost, making it difficult to adapt to the screening needs of power battery consistency in multiple scenarios. Data analysis has yet to play an integral role in the screening process; thus, fast and efficient battery screening technology has become one of the critical technologies for the large-scale application of retired batteries. Additionally, the existing echelon utilization technology cannot solve the problems of poor consistency; moreover, the degradation of the reorganized battery cascade operation is fast and the aging pattern is difficult to predict, posing significant safety hazards. The echelon utilization of retired power batteries still needs to achieve breakthroughs associated with large-scale applications, such as consistency management, dynamic safety monitoring, and regulation. Although the demonstration application of echelon utilization battery energy storage systems achieved satisfactory results initially, it still faces technical challenges such as system safety and economy. This study summarizes the research status of key technologies, such as sorting, evaluation, screening, detection, recombination, balancing, and safety of retired power batteries, by exploring recent relevant literature. It characterizes the industrial policies and national industry standards related to the echelon utilization of retired power batteries, which is expected to provide a reference for the reasonable use of large-scale retired power batteries.

Key words: electrochemical energy storage, retired power battery, echelon utilization, echelon utilization standards
