AI Customer ServiceAt a temperature of 250 degrees, the nickel-salt mixture can be used to store energy. Now, one might assume that a hot battery also burns much faster. But that is not the
AI Customer ServiceWhen the battery temperature exceeds about 150°C there is a large risk for thermal runaway. Once thermal runaway has been initiated, either the cell or its safety valve will burst and release toxic gas. As thermal runaway propagates, more battery cells will fail to generate more smoke and toxic gases.
Once the battery started to burn, the already intense fire becomes more disastrous. Finally, the burning of battery slows down but remains robust for a very long time, which is typical for a LFP battery fire.

Secondly, as shown in Fig. 7 b, when it is exposed to a high temperature above 130 °C, the electrolyte experiences the second radical reaction, turning to solid state from previous liquid state. The full LFP/TSE/Li battery can operate well even at 150 °C.
The battery ignites when the battery temperature reaches approximately 175–180 °C. This critical temperature is related to an internal short circuit of the battery, which results from the melting of the separator. The maximum temperature of the flame can reach 1500 °C.
As mentioned previously, local overheating will induce metallic dendrites, which will cause fractures, pulverization, and internal short circuit. Thermal stress/thermal strain can be generated by temperature increase and high expansion coefficient can lead to volume changes and battery deformation.
Compared to the electrical energy stored in the battery, the thermochemical energy released from the battery fire, including both the thermal runaway heat inside the battery (i.e., the internal heat) and flame sustained by the flammable gases injected from the battery (i.e., the flame heat), is much higher [18, 39, 40].
