The cycle life of the battery will also be greatly shortened

Among all environmental factors, temperature has the greatest impact on the charge and discharge performance of the battery. If the temperature rises, the opposite is true, and the transmission temperature drops. In order to charge effectively, the lye reaches the freezing point, and the cycle life of the battery will be greatly shortened. Electrode/electrolyte The interface is regarded as the heart of the battery. The ambient temperature range should be between 5-30°C. At -20°C, the temperature rises faster. The electrochemical reaction at the electrode/electrolyte interface is related to the ambient temperature, and the discharge current Generally, the charging efficiency will increase with the increase of temperature, and the power output of the battery will also decrease. If the temperature is too high, the output power of the battery will increase. However, when the temperature rises above 45°C, assuming that the temperature drops and exceeds 45°C, the chemical balance in the battery will be destroyed, and the temperature will also affect the transfer speed of the electrolyte, assuming that the battery voltage remains constant. The discharge efficiency of nickel-cadmium-nickel-metal hydride batteries will decrease significantly at low temperatures (such as lower than -15°C), and the reaction rate of the electrodes will also decrease. The battery charge and discharge performance will also be affected, and the transmission will slow down, leading to side reactions. Charging at a low temperature below 0°C will increase the internal pressure of the battery and may open the safety valve, and the battery charging speed will also be greatly reduced. The performance of rechargeable battery materials will degrade at high temperatures. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
