Title: Lithium-sulfur batteries

Abstract

A lithium-sulfur electrochemical cell includes a cathode including elemental sulfur; an anode including elemental lithium; and an electrolyte including a salt and a non-polar fluorinated ether solvent. Alternatively, a lithium-sulfur electrochemical cell may include an anode; an electrolyte; and a cathode including a polytetrafluoroethylene-coated carbon paper and sulfur.
