2H,3H-Decafluoropentane Endorsed Localized High Concentration Electrolyte for Low-Temperature Lithium-Metal Batteries.

A lithium-metal battery's electrochemical performance is affected by the kinetics of desolvation and ion transport at low temperatures. Here, we propose a low-temperature lithium-metal battery electrolyte. 1,2-Dimethoxyethane (DME) is used as the solvent, 2H,3H-decafluoropentane (HFC) as the diluent, and a high concentration of lithium bis(fluorosulfonyl)imide (LiFSI) as the solute.
