Introduction
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.
Through the research on the module temperature rise and battery temperature difference of the four flow channel schemes, it is found that the battery with the serial runner scheme is better balanced and can better meet the operating temperature requirements of lithium iron phosphate batteries.
At the same ambient temperature, the lithium iron battery is discharged to the cutoff voltage at 1 C and 3 C, and the average increase in the temperature of the lithium iron battery cell area reaches 4.5 K and 15 K, respectively.
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:
