This review is expected to provide a deepened understanding of the working mechanisms of rechargeable batteries at low temperatures and pave the way for their development and diverse practical applications in the future. Low temperature will reduce the overall reaction rate of the battery and cause capacity decay.
Guo et al. proposed a hybrid DC-AC fast heating method to preheat LIB at low temperatures and high charge states. The method used a fractional-order circuit model to derive the total impedance of the circuit, which was used to calculate the optimal excitation parameters for DC-AC preheating under different conditions.
By comparing and analyzing the advantages and disadvantages of the existing mainstream heating methods, the main conclusions are as follows: Preheating LIB at low temperatures is the ultimate goal of improving pack capacity and large rate charge/discharge performance.

Briefly, the key for the electrolyte design of low-temperature rechargeable batteries is to balance the interactions of various species in the solution, the ultimate preference is a mixed solvent with low viscosity, low freezing point, high salt solubility, and low desolvation barrier.
However, due to the large latent heat of PCM, the temperature of the initial stage of the battery increased slowly in a cold environment. Additionally, the larger thermal mass of the PCM prevented the cell from self-heating during long-term application in low temperatures, resulting in a loss of power and capacity.
