What is the impact of low temperature on lithium battery?

1.The use of lithium-ion batteries at low temperatures is limited by the fact that they cannot be recharged at low temperatures, in addition to the severe decline in discharge capacity.Due at low temperature charging, lithium ion embedding and lithium plating on the graphite electrode of the battery coexist and compete with each other.

2.The internal resistance of the battery increases obviously with the decrease of temperature. The lower the battery charge is, the greater the internal resistance is, and this trend remains unchanged with the change of temperature.

3.The influence of low temperature on the charging and discharging efficiency of lithium ion battery. In the discharge process, a large amount of electric energy is consumed in the internal resistance heating.

4.Easily form lithium condensation in the cathode, irreversibly affecting the battery life.
