Push–Pull Electrolyte Design Strategy Enables High-Voltage Low-Temperature Lithium Metal Batteries

Опубликована: Сен. 27, 2024

Lithium (Li) metal batteries hold significant promise in elevating energy density, yet their performance at ultralow temperatures remains constrained by sluggish charge transport kinetics and the formation of unstable interphases. In conventional electrolyte systems, lithium ions are tightly locked solvation structure, thereby engendering difficulty desolvation process further exacerbating solvent decomposition. Herein, we propose a new push-pull design strategy, utilizing molecular electrostatic potential (ESP) screening to identify 2,2-difluoroethyl trifluoromethanesulfonate (DTF) as an optimal cosolvent. Importantly, DTF exhibits moderate ESP minimum (-21.0 kcal mol

Abstract Ether‐based electrolytes show great potential in low‐temperature lithium metal batteries (LMBs) for their low viscosity and decent reduction stability. However, conventional ethers with multidentate chelate sites suffer from oxidation stability high desolvation energy barrier due to the strong coordination between oxygen Li + . Herein, cyclic tetrahydropyran (THP) a unidentate site is designed as solvent, fluoroethylene carbonate (FEC) nitrate (LiNO 3 ) serve additives LMBs. The strain effect endow THP weak affinity ions, which accelerates process induces anion‐derived electrode/electrolyte interface at temperature. formed inorganic‐rich further improves expedites interfacial ion transportation.
