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.
Stable operation of rechargeable lithium-based batteries at low temperatures is important for cold-climate applications, but is plagued by dendritic Li plating and unstable solid–electrolyte interphase (SEI). Here, we report on high-performance Li metal batteries under low-temperature and high-rate-charging conditions.
Preferred adsorption and favor H-transfer reactions of NO 3 – anions induce an inorganic-rich CEI. The designed electrolyte possesses high reversibility and dendrite-free ability. The multi-component electrolyte with increased entropy is a good solution for low-temperature Li metal batteries.
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.
Electrolytes for low temperature, high energy lithium metal batteries are expected to possess both fast Li+ transfer in the bulk electrolytes (low bulk resistance) and a fast Li+ de-solvation process at the electrode/electrolyte interface (low interfacial resistance).
Consequently, dendrite-free Li deposition was achieved, Li anodes were cycled in a stable manner over a wide temperature range, from −60 °C to 45 °C, and Li metal battery cells showed long cycle lives at −15 °C with a recharge time of 45 min. Our findings open up a promising avenue in the development of low-temperature rechargeable batteries.
