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.
In this work, the 18650-type lithium iron phosphate batteries under different heating powers and heating quantities were investigated using copper slug battery calorimetry. The battery thermal failure performance and thermal process were characterized by temperature, mass loss the internal heat generation.
The results revealed that bottom heating accelerates the propagation speed of internal TR, resulting in higher peak temperatures and increased heat generation. Wang et al. examined the impact of the charging rate on the TR of lithium iron phosphate batteries.
In this work, an experimental platform composed of a 202-Ah large-capacity lithium iron phosphate (LiFePO4) single battery and a battery box is built. The thermal runaway behavior of the single battery under 100% state of charge (SOC) and 120% SOC (overcharge) is studied by side electric heating.
Heat Transfer Model During the TR process of lithium-ion batteries, heat exchange occurs between the battery and its surroundings, resulting in changes in the battery’s own temperature. The heat transfer equations are given in references [38, 39].
Unlike ternary Li-ion batteries that produce jet fire owing to thermal runaway, lithium iron phosphate Li-ion batteries show obvious difference. If there is no combustible material at the discharge port of lithium iron phosphate Li-ion batteries, there will not exist open flame.
