Abstract
An electrolyte capable of lip roving the stability of a lithium-metal battery is provided. The electrolyte includes an organic solvent, a cosolvent, which is different from the organic solvent and includes a fluorine-based compound, and an additive having a lower lowest unoccupied molecular orbital (LUMO) value than the organic solvent.
Claims10
An electrolyte, comprising:
- an organic solvent;
- a cosolvent, wherein the cosolvent is different from the organic solvent and comprises a fluorine-based compound;
- and
- an additive having a lower lowest unoccupied molecular orbital (LUMO) value than the organic solvent,
- wherein the additive comprises difluorophosphate (LiPO2F2),
- wherein the organic solvent comprises 1,2-dimethoxyethane,
- wherein the cosolvent comprises 1,1,2,2-tetraflouroethyl-1H, 1H,5H-octafluoropentyl ether (TFOFE), and
- wherein a volume ratio of the organic solvent and the cosolvent is 5:5 to 9:1.
