<p>A high performance lithium-sulfur battery cell includes the following features: (a) a negative electrode including a metal or an ion of the metal; (b) a positive electrode comprising an electronically conductive material; and (c) a liquid catholyte including a solvent and dissolve electrochemically active material comprising sulfur in the form of at least one of a sulfide of the metal and a polysulfide of the metal. Such battery cells are characterized by an energy density, calculated based upon a laminate weight, of at least about 400 Watt-hours/kilogram when discharged at a rate of at least 0.1 mA/cm2. Cells meeting these criteria often find use as primary cells.</p> |
