Web14 feb. 2024 · The battery goes into the thermal runaway. In the temperature range of 180–250°C, an exothermic reaction heat occurs between the lithium iron phosphate positive electrode and the electrolyte, and when the temperature is above 200°C, the EC/DEC electrolyte decomposes, resulting in the generation of a lot of heat. WebIf you heat a battery cell to somewhere above 130°C then exothermic chemical reactions inside the cell will increase the temperature and further reactions will take place. The result is an uncontrolled runaway and increase in temperature. The cell should vent in a controlled manner with fire and molten material.
