Abstract:

Lithium-ion batteries have been widely used in manufacturing and daily life as common energy storage and power device. However, thermal runaway can occur under abusive conditions, so its safety must be investigated. The thermal runaway simulation has significant advantages over the experimental method and is an important tool for studying the thermal runaway of lithium-ion batteries. This paper analyzes the research status of thermal runaway simulation from three aspects, thermal runaway simulation, thermal propagation simulation, and the application of thermal runaway simulation. The heat generation mechanism and simulation method of thermal runaway caused by different inducements (thermal abuse, mechanical abuse, and electrical abuse), the research status of the simulation in heat spread in the battery pack and how to restrain the heat spread, and the research on thermal runaway prediction method are all introduced emphatically. The thermal runaway model is already accurate enough to simulate the main exothermic side reactions when the battery thermal runaway occurs. On the other hand, the battery is complex, with chemical reactions and physical changes, and the parameters are difficult to measure and calculate. As a result, further research into the thermal runaway simulation of lithium-ion batteries is required.

Key words: lithium-ion battery, thermal runaway, simulation, thermal abuse
