Why will the lithium-ion battery life will fall?

Electric cars will decline in the lithium-ion battery life in winter, and there are several originals, first and the internal electrodes of the battery and the electrolyte have a certain relationship. For the power lithium-ion battery of electric vehicles, when the temperature is relatively low, The active material of the positive electrode material, the lower the temperature, the worse activity, the characteristics of the electrochemical chemistry inside the battery, which make the battery have a rapid decrease in the battery, resulting in a large internal resistance in the battery. All lithium ions inside the lithium ion battery are stored to the positive electrode, and the negative electrode is composed of graphite (carbon).

An electrolyte and diaphragm are included between the positive and negative two poles. The discharge process of the lithium-ion battery is the movement of lithium ions from the negative electrode to the positive electrode, and the electric energy required for the electric vehicle supply through the discharge of the lithium ion battery. In the case where the temperature is lowered, the process of this charge and discharge will slow down.

Therefore, the current of the discharge is small, and the capacity of the battery will become smaller. The logo operating temperature of the lithium-ion battery is 0-40 ¡ã C, but in fact, when the temperature is below 25 ¡ã C, a certain degree of performance reduction occurs: the battery capacity is reduced, the discharge speed is slow, the battery output power is small, et.
