Abstract
An electrolyte includes a lithium (Li) salt, a fluorinated solvent, a 1,3-dioxaolane (DOL) solvent, a 1,2-dimethyoxyethane (DME) solvent, a lithium polysulfide (LiPS), and a lithium nitrate (LiNO3). Lithium sulfur electrochemical devices, such as lithium electrochemical cells and lithium-sulfur batteries, such as lithium-sulfur rechargeable (secondary) batteries include an electrolyte that includes a lithium (Li) salt, a fluorinated solvent, a 1,3-dioxaolane (DOL) solvent, a 1,2-dimethyoxyethane (DME) solvent, a lithium polysulfide (LiPS), and a lithium nitrate (LiNO3).
