AI Customer ServicePlus, it’s not ideal for cold-weather batteries for weight-sensitive applications, such as high-altitude drones and satellites. Many researchers are attempting to improve battery performance at low temperatures by focusing on the electrolytes that shuttle lithium ions between battery electrodes.
By redesigning the battery electrolyte, researchers have now made a battery that works at temperatures down to -20 °C. Compared to other cold-weather batteries that researchers have reported so far, this one has a record-breaking lifetime of over a year. Today’s batteries work well at temperatures between 0 °C and 40 °C.

The cooling efficiency depends on the L/D ratio; at L/D = 36.1 gives a better performance. Increasing the flow rate enhanced the temperature reduction of the battery. Also, lowering the fluid's inlet temperature significantly reduces the battery pack's temperature. Need to optimize the inlet flow rate and temperature.
This increase in temperature within the battery cell is due to the interplay of thermal effects within the cell. The heat generated in one cell affects adjacent cells, and this thermal coupling extends to the entire module, propagating heat throughout the battery pack.
In a conventional electrolyte, as the temperature dips, the ions and solvent molecules aggregate into larger clusters, restricting their movement and lowering the entropy. “Such a decreased entropy leads to the precipitation of salt,” says Lu, and thus to the performance decay of the battery.
