On the one hand, the decrease in temperature will result in a decrease in the activity of the active electrolyte in the lithium ion battery and an increase in the concentration, which in turn will slow down the deintercalation rate of lithium ions during the discharge process [ 27 ].
At −40 °C, the battery capacity of lithium iron phosphate remains 46.6%, that of lithium manganate is 36.8%, and that of lithium cobaltate is only 11.7%. Considering the discharge efficiency and cycle life, the best working temperature of a lithium-ion battery is 20–50 °C.
This work is to investigate the impact of relatively harsh temperature conditions on the thermal safety for lithium-ion batteries, so the aging experiments, encompassing both cyclic aging and calendar aging, are conducted at the temperature of 60 °C. For cyclic aging, a constant current-constant voltage (CC-CV) profile is employed.
When the ambient temperature is higher than 25 °C and lower than 55 °C, the discharge capacity of the battery will increase as the temperature rises. This is due to the increase in the activity of the internal materials of the battery, the faster the deintercalation of lithium ions, as well as the decrease in internal resistance.
Lithium plating is a specific effect that occurs on the surface of graphite and other carbon-based anodes, which leads to the loss of capacity at low temperatures. High temperature conditions accelerate the thermal aging and may shorten the lifetime of LIBs. Heat generation within the batteries is another considerable factor at high temperatures.
For example, the heat generation inside the LIBs is correlated with the internal resistance. The increase of the internal temperature can lead to the drop of the battery resistance, and in turn affect the heat generation. The change of resistance will also affect the battery power.
