For large-capacity lithium-ion batteries, Liu et al. studied the thermal runaway characteristics and flame behavior of 243 Ah lithium iron phosphate battery under different SOC conditions and found that the thermal runaway behavior of the battery was more severe and the heat production was more with the increase of SOC.
The paper studied the gas production and flame behavior of the 280 Ah large capacity lithium iron phosphate battery under different SOC and analyzed the surface temperature, voltage, and mass loss of the battery during the process of thermal runaway comprehensively. The thermal runaway of the battery was caused by external heating.
This intensive investigation can contribute toward ensuring thermal stability and reliability of LFP batteries from various perspectives. Summary This study investigates the thermal runaway (TR) pathways of a lithium iron phosphate (LFP) battery to establish important considerations for its operation and design.
Thermal runaway (TR) and resultant fires pose significant obstacles to the further development of lithium-ion batteries (LIBs). This study explores, experimentally, the effectiveness of liquid nitrogen (LN) in suppressing TR in 65 Ah prismatic lithium iron phosphate batteries.
The fire behaviors of 22 Ah LiFePO 4 /graphite batteries are investigated. 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.
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.
