As the number of cells increases, the thermal runaway occurred at lower external heating, indicating a higher fire risk. Moreover, a simplified heat transfer model was proposed to demonstrate the effects of pressure and battery pile size on thermal-runaway criteria.
The main conclusions include. Heat generation inside battery cell during thermal runaway process mainly includes the short circuit heat and the side reaction heat. The side reaction heat takes the main part and forms when the cell temperature reaches the onset point.
Additionally, the gas generation mechanism and the combustion characteristic of flammable gas are also analyzed. The main conclusions include. Heat generation inside battery cell during thermal runaway process mainly includes the short circuit heat and the side reaction heat.
Alleviating and restraining thermal runaway (TR) of lithium-ion batteries is a critical issue in developing new energy vehicles. The battery state of charge (SoC) influence on TR is significant. This paper performs comprehensive modeling and analysis with the non-uniform distribution of SoCs at the module level.
Thermal runaway is a common failure of battery, when the heat release rate from internal chain reactions larger than the external cooling rate. When thermal runaway occurs, LIBs rapidly release a large amount of heat and eject flammable and toxic materials (Sun et al., 2020 ).
