Lithium Iron Phosphate Battery performance will be changed by temperature

2021-06-05

The effect of temperature on the overpotential is more significant. The higher the temperature, the smaller the overpotential, and the easier the electrode reaction will proceed.
1. Charge transfer resistance on the contact surface between alloy and electrolyte;
2. The diffusion resistance of hydrogen atoms from the alloy body to the surface. The increase in temperature accelerates the diffusion of hydrogen atoms and the speed of charge transfer, promotes the progress of the electrode reaction, and reduces the over potential of the reaction, so the discharge capacity of the battery increases. Similarly, the discharge power capacity of the battery will also increase under high temperature conditions. .

3. For lithium iron phosphate battery, the discharge capacity drops sharply under the same low temperature conditions, but the discharge capacity at high temperatures is not lower than normal temperature, and sometimes slightly higher than normal temperature capacity.
