With the fall of the ambient temperature, the battery impedance R increasing, omics heating power P will produce more of the internal resistance of the battery, the temperature rise is faster, the temperature after the cell activity increased faster, resistance decreases more quickly, improve the battery output voltage is more obvious.
Although some heating strategies can support battery work, the additional heating accessories and temperature management systems can increase energy consumption and cost. The direct optimization of the low-temperature electrolyte system is the most cost-effective and fastest way to continue LIB work.
At low temperatures, the Li + -desolvation process becomes difficult, and the transport speed of Li-ion through the SEI layer slows down. 33–35 These processes can be improved by modifying the electrode–electrolyte interface, including different compositions of the electrolytes and improved SEI/CEI properties.
From the same rate discharge curve, it can be seen that with the decrease of temperature, the trend of voltage rise in the initial stage of battery discharge is more obvious, mainly because the omics heat power equation produced by the battery internal resistance is as follows: P =I2R P = I 2 R
