The thermal runaway (TR) of lithium iron phosphate batteries (LFP) has become a key scientific issue for the development of the electrochemical energy storage (EES) industry. This work comprehensively investigated the critical conditions for TR of the 40 Ah LFP battery from temperature and energy perspectives through experiments.
Under the open environment, the critical thermal runaway temperature Tcr of the lithium iron phosphate battery used in the work is 125 ± 3 °C, and the critical energy Ecr required to trigger thermal runaway is 122.76 ± 7.44 kJ.

Mao and Liu et al. [, , ] investigated the thermal runaway and flame behavior of high-capacity lithium iron phosphate batteries (243 Ah and 300 Ah), and further analyzed the thermal hazards of the batteries when thermal runaway occurs.
In a study by Zhou et al. , the thermal runaway (TR) of lithium iron phosphate batteries was investigated by comparing the effects of bottom heating and frontal heating. The results revealed that bottom heating accelerates the propagation speed of internal TR, resulting in higher peak temperatures and increased heat generation.
A heating plate is developed to induce the Li-ion battery to thermal runaway. The temperature of cell and flame, heat release rate and other key parameters are quantified. The relationship between thermal runaway and fire behaviors is analyzed. The mechanism and phenomenon related to SOCs are discussed based on the energy balance of the cell.
The results demonstrated that increasing the onset temperature of thermal runaway can effectively improve the performance of overcharging. Jin et al. developed a three-dimensional simulation model to investigate the comprehensive effects of heating area and heating power on the thermal runaway of lithium-ion batteries.
