Reduced vapor pressure liquefied gas electrolytes using high concentration salt

Abstract

Disclosed are novel electrolytes based on liquefied gas and high concentration of salt in liquefied gas electrolytes. Unlike common electrolytes, liquefied gas electrolytes utilize solvents which are gaseous under standard conditions. The current disclosure describes electrolytes which consist of a solvent comprised of one or more solvents, wherein one or more of those solvents are a liquefied gas solvent, and a salt or combination of salts at high enough concentration such that the combination of solid salt and liquefied gas solvent results in a reduced vapor pressure electrolyte or even a liquid electrolyte mixture with vapor pressure below that of atmospheric pressure at a temperature of 293.15K.

Dependencies are inferred from the claim text.
