The Effect Of Temperature On Battery Performance

During the charging and discharging of the battery, an electrochemical reaction occurs on the battery electrodes. The higher the temperature is, the activity of each active material in the battery increases, the viscosity of the electrolyte decreases, and the resistance decreases, so the electrochemical reaction is easy to carry out, otherwise it is not easy to carry out. The lower the temperature during discharge, the lower the discharge capacity. At a particularly low temperature, the discharge capacity will be greatly reduced, and the opposite is true when the temperature is high; Electricity. On the contrary, the higher the temperature, the better the charging acceptance ability, which is easy to cause overcharging. Therefore, it is required to reduce the charging voltage so as not to cause overcharging. The change of this temperature directly affects the charging and discharging performance of the battery.
