Since the battery is in a constant temperature environment of −20 °C, the heat convection between the battery and the air can not be ignored. When the side was heated, the heat generated by the electric energy that the heating film consumed was mainly transferred through two paths: horizontal thermal conduction, which increased the cell temperature, and heat

The inlet temperature, heating time, and external ambient temperature of the battery heating system all have an effect on the heat balance performance. The temperature uniformity is poor due to the narrow space, and the temperature of the water heating the battery is also decreased with the increase of the distance the water flows through .
The SP heating at 90 W demonstrates the best performance, such as an acceptable heating time of 632 s and the second lowest temperature difference of 3.55 °C. The aerogel improves the discharge efficiency of the battery at low temperature and high discharge current.
The increase in operating temperature also requires a more optimized battery design to tackle the possible thermal runaway problem, for example, the aqueous–solid–nonaqueous hybrid electrolyte. 132 On the cathode side, the formation of LiOH will eliminate the attack of superoxide on electrodes and the blocking of Li 2 O 2.
In addition to liquid cooling, heat pipes can help make up for the low specific heat capacity of air. Using CHP, Behi et al. proved that the liquid-cooling-coupled heat pipe system outperforms an air-cooling-coupled heat pipe system in terms of cooling effect, and the maximum temperature of the battery is reduced by about 30%.
Further promoting the temperature increase, a higher local temperature will destroy battery consistency. It may also lead to the occurrence of thermal runaway and cause safety accidents. In a low-temperature environment, the battery’s temperature rise is uneven, exacerbating battery inconsistency and reducing battery life.
