Abstract:

Thermal runaway of lithium-ion batteries is the core issue of current electrochemical energy storage power stations regarding safety. Accurate and detailed description of the battery thermal runaway is the premise to realize the active safety warning of energy storage power stations. However, lithium-ion battery is an electrochemical system with complex nonlinear characteristics, which exhibits multi-dimensional signal characteristics during their thermal runaway evolution. It is difficult to comprehensively monitor batteries' safety and health status only by a single signal characteristic. Therefore, studying the evolution and coupling mechanism of multi-dimensional signals in the battery thermal runaway is essential. This review systematically investigated the evolution laws of characteristic signals in the four dimensions of thermal, electricity, machinery, and gas during the thermal runaway of lithium-ion batteries and analyzed the coupling characteristics between different signals. Furthermore, an active safety early warning method has prospected for energy storage batteries based on multi-dimensional sensing signals.

Key words: lithium-ion battery, thermal runaway, multi-signal coupling, safety warning
