Here, we first review the main interfacial processes in lithium-ion batteries at low temperatures, including Li + solvation or desolvation, Li + diffusion through the solid electrolyte interphase and electron transport.
Modern technologies used in the sea, the poles, or aerospace require reliable batteries with outstanding performance at temperatures below zero degrees. However, commercially available lithium-ion batteries (LIBs) show significant performance degradation under low-temperature (LT) conditions.
Previous attempts to improve the low-temperature performance of lithium-ion batteries 4 have focused on developing additives to improve the low-temperature behaviour of electrolytes 5, 6, and on externally heating and insulating the cells 7, 8, 9.
However, commercially available lithium-ion batteries (LIBs) show significant performance degradation under low-temperature (LT) conditions. Broadening the application area of LIBs requires an improvement of their LT characteristics.
Two main approaches have been proposed to overcome the LT limitations of LIBs: coupling the battery with a heating element to avoid exposure of its active components to the low temperature and modifying the inner battery components. Heating the battery externally causes a temperature gradient in the direction of its thickness.
