Several factors contribute to this: Overcharging: Pushing more energy into the battery than its design allows causes excessive heat and can initiate thermal runaway. Short circuits: An internal or external short circuit creates a low-resistance path for current flow, generating intense heat. This can rapidly heat the battery beyond its safe operating temperature. Over-discharging: Draining the battery completely can damage the internal components, leading to heat generation and potential thermal runaway. Manufacturing defects: Faulty cells or poor manufacturing processes can create internal weaknesses or inconsistencies that increase the risk of thermal runaway. External heat: Exposure to extreme temperatures (high heat from external sources) can directly contribute to the overheating of the battery and trigger the process. Once thermal runaway begins, the propagation of the fire is rapid. The high temperatures generated within the cell cause the electrolyte to decompose, releasing flammable gases. These gases can ignite, causing further heating and releasing even more gases in a positive feedback loop. The rapid heating and combustion of the flammable materials lead to a quickly spreading fire. The resulting flames can be intense and difficult to extinguish, particularly with larger battery packs. Furthermore, the battery's design and casing material can influence fire spread. A tightly packed battery pack may create conditions conducive to more rapid fire spread due to heat confinement.
LiFePO4 battery fires start from thermal runaway caused by overcharging, short circuits, over-discharging, defects, or external heat. This causes rapid heating, flammable gas release, and intense, fast-spreading fires.
