However, faced with diverse scenarios and harsh working conditions (e.g., low temperature), the successful operation of batteries suffers great challenges. At low temperature, the increased viscosity of electrolyte leads to the poor wetting of batteries and sluggish transportation of Li-ion (Li +) in bulk electrolyte.
At low temperatures, the critical factor that limits the electrochemical performances of batteries has been considered to be the sluggish kinetics of Li +. 23,25,26 Consequently, before seeking effective strategies to improve the low-temperature performances, it is necessary to understand the kinetic processes in ASSBs.
Last but not the least, battery testing protocols at low temperatures must not be overlooked, taking into account the real conditions in practice where the battery, in most cases, is charged at room temperature and only discharged at low temperatures depending on the field of application.
After heating the bottom of the battery pack with PTC material for 3 hours, the average temperature of the external cells was 2.57°C, while the temperatures of the internal cells were －2.63 and －2.09°C.
Lithium-ion batteries are in increasing demand for operation under extreme temperature conditions due to the continuous expansion of their applications. A significant loss in energy and power densities at low temperatures is still one of the main obstacles limiting the operation of lithium-ion batteries at sub-zero temperatures.
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.
