摘要:

安全性是锂离子电池储能系统的重要议题,探究锂电池储能系统安全事故成因,开展储能系统安全状态的评价与早期预警及事故风险的管控与防护等研究具有重要意义。本文立足于韩国公开的其国内近期发生的锂电储能系统安全事故调查报告,对电池本体、外部激源、运行环境及管理系统等引致安全事故的因素进行了分析,梳理了四类因素作用下电池及系统安全事故的触发及演化规律,探讨了四类因素间的相互影响机制,总结经验教训的同时提出了锂电储能系统安全管理的发展方向。

Abstract:

Safety issues are an important topic concerning lithium-ion battery energy storage systems. Exploring the causes of safety accidents and conducting intensive research on evaluations and early warnings of the safety status, as well as management and control and the prevention of safety accidents, have great significance. Based on the investigation report released on safety accidents that recently occurred in South Korea, we carefully analyzed four aspects of the factors involved, namely, the battery itself, the external excitation sources, the environment and operating conditions, and the related management systems, to examine the underlying mechanisms triggering and furthering the safety accidents. We discuss the interactions in-between the above four aspects. Moreover, we summarize these experiences and draw lessons from them, as well as propose research and development directions for the safety management of lithium-ion battery energy storage systems.

Key words: lithium-ion battery, electricity storage, safety accidents, thermal runaway, early warning
