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.
It is found that when the lithium iron phosphate battery is charged, reversible heat first manifests itself as heat absorption, and then soon as exotherm after around 30% SOC, while the reverse for discharge. The total heat generation of lithium iron phosphate batter-ies during charging is higher than that during discharging.

There is less capacity for power storage in the battery when the temperatures are cold. You should never charge a lithium battery when the temperatures are below 32°F as it can cause the lithium ions to bind into lithium metal and short the battery internally. Lithium-ion batteries heat up when you are charging them at very high rates. If the

The total heat generation of lithium iron phosphate batteries during charging is higher than that during discharging.
In addition, a three-dimensional heat dissipation model is established for a lithium iron phosphate battery, and the heat generation model is coupled with the three-dimensional model to analyze the internal temperature field and temperature rise characteristics of a lithium iron battery.

As the lithium iron battery functions, an electrochemical reaction occurs on the spherical surface of the electrode. According to the operating current of the battery, the density of the reactive lithium-ion on the surface of each particle can be calculated. The Butler–Volmer kinetic equation can be obtained:
There is no generation of side reaction heat in the lithium iron battery. The positive and negative active material is composed of particles of uniform size. The change in the volume of the electrode during the reaction is negligible, and the electrode has a constant porosity.
It is difficult for lithium-ions to diffuse to the particle surface and react with the electrolyte at subzero temperature. As a result, the SOC on the NE surface decreases rapidly, causing the deficiency of lithium-ions and increasing the resistance and thus the battery heat generation significantly.
