💡 Novelty & Significance:
The novelty is a solvation-equilibrium-locked electrolyte using dimethyl sulfite and an ionic-liquid co-solvent, which keeps anion-rich Li⁺ solvation nearly invariant from −60 to 60 °C. This enables Li||NMC811 operation from −85 to 120 °C, pouch cells after −122.9 °C cooling, and a 565 Wh kg⁻¹ Li||Ni90 pouch cell, establishing a molecular design principle for ultrawide-temperature lithium-metal batteries.
