What is the effect of ambient temperature on battery performance?
Among all environmental factors, temperature has the greatest influence on the charge and discharge performance of the battery. The electrochemical reaction at the electrode/electrolyte interface is related to the ambient temperature, and the electrode/electrolyte interface is regarded as the heart of the battery.
If the temperature drops, the reaction rate of the electrode also decreases. Assuming that the battery voltage remains constant, the discharge current decreases, and the power output of the battery also decreases.
If the temperature rises, the opposite is true, that is, the battery output power will rise, and the temperature also affects the transfer speed of the electrolyte. The temperature rises, the transfer temperature decreases, the transfer slows down, and the battery charge and discharge performance is also affected. However, if the temperature is too high, exceeding 45 will damage the chemical balance in the battery and cause side reactions.
