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.
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 . Fig. 8. Liquid preheating .
The prerequisite to support low-temperature operation of batteries is maintaining high ionic conductivity. In contrast to the freezing of OLEs at subzero temperatures, SEs preserve solid state over a wide temperature range without the complete loss of ion-conducting function, which ought to be one of potential advantages.
Specifically, under extreme low-temperature conditions , the reaction rate and charge/discharge capacity of a battery will be seriously degraded, further causing frostbite and permanent damage to the battery .
In general, from the perspective of cell design, the methods of improving the low-temperature properties of LIBs include battery structure optimization, electrode optimization, electrolyte material optimization, etc. These can increase the reaction kinetics and the upper limit of the working capacity of cells.
By applying rectangular pulse waveform at 10 A and 30 Hz, the proposed strategy could heat batteries from −24 °C to 25.6 °C within 600 s. Besides, the pulsed self-heating strategy at low temperatures also ensured fast and safe preheating performance. .
