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
