Anion-Modulated Solvation Sheath and Electric Double Layer Enabling Lithium-Ion Storage From −60 to 80 °C

Journal of the American Chemical Society, Год журнала: 2025, Номер unknown

Опубликована: Янв. 27, 2025

Current lithium batteries experience significant performance degradation under extreme temperature conditions, both high and low. Traditional wide-temperature electrolyte designs typically addressed these challenges by manipulating the solvation sheath selecting solvents with melting/boiling points. However, solvent-mediated solutions, while effective at one extreme, invariably fail opposite end due to inherent difficulties in maintaining solvent stability across wide temperatures. Herein, we report use of main salt simultaneously address interfacial extremely low This approach is different from conventional strategies. As a proof concept, utilized nitrate (LiNO3) establish an anion-controlled structure electric double layer. The formulated electrolytes exhibited remarkable extremes, retaining 56.1% capacity -60 °C sustaining 400 stable cycles 80 °C. In contrast, based on current strategies failed operate could not exceed 50 By shifting focus rather than solvent, our work offers possibility addressing enduring broad range.
