Can a solvent polarity gradient improve the low-temperature performance of lithium-ion batteries?

Multiple requests from the same IP address are counted as one view. Improving the low-temperature performance of lithium-ion batteries is critical for their widespread adoption in cold environments. In this study, we designed a novel LHCE featuring a solvent polarity gradient, designed to maximize both room- and low-temperature ion mobility.

How to tame low-temperature lithium batteries?

Obviously, formulating electrolytes is an effective approach to tame the low-temperature challenges of Li metal batteries, while more efforts should be devoted to establishing the design criterion for such electrolytes. 3.2. Cathode modification

Can Li stabilizing strategies be used in low-temperature batteries?

The Li stabilizing strategies including artificial SEI, alloying, and current collector/host modification are promising for application in the low-temperature batteries. However, expeditions on such aspects are presently limited, with numerous efforts being devoted to electrolyte designs. 3.3.1. Interfacial regulation and alloying

Which electrolyte is a good solution for low-temperature lithium batteries?

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.

Can Li metal batteries work at a low temperature?

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.

How does low temperature affect the performance and safety of lithium ion batteries?

Especially at low temperature, the increased viscosity of the electrolyte, reduced solubility of lithium salts, crystallization or solidification of the electrolyte, increased resistance to charge transfer due to interfacial by-products, and short-circuiting due to the growth of anode lithium dendrites all affect the performance and safety of LIBs.
