However, the low-temperature Li metal batteries suffer from dendrite formation and dead Li resulting from uneven Li behaviors of flux with huge desolvation/diffusion barriers, thus leading to short lifespan and safety concern.
The stable operation of lithium-based batteries at low temperatures is critical for applications in cold climates. However, low-temperature operations are plagued by insufficient dynamics in the bulk of the electrolyte and at electrode|electrolyte interfaces.
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.
Additionally, ether-based and liquefied gas electrolytes with weak solvation, high Li affinity and superior ionic conductivity are promising candidates for Li metal batteries working at ultralow temperature.
LIBs can store energy and operate well in the standard temperature range of 20–60 °C, but performance significantly degrades when the temperature drops below zero [2, 3]. The most frost-resistant batteries operate at temperatures as low as −40 °C, but their capacity decreases to about 12% .
The resulted SEI typically is comprised of increased organic intermediate products, relating to uneven Li + transport and deposition. In addition, dendritic Li deposits and localized short-circuits of batteries are more frequently at low temperature. Additionally, the corrosion behavior of Li at low temperature should also not be overlooked.
