Lithium/organosulfur redox cell having protective solid electrolyte barrier formed on anode and method of mixing the same
This patent describes a solid lithium-organosulfur redox cell. It comprises: a solid lithium anode formed from a material selected from the class consisting of elemental lithium and one or more lithium base alloys comprising over 50 wt. % lithium or mixtures thereof; a liquid organosulfur cathode having the formula of (R(S){sub {ital Y}}){sub {ital N}} where y = 1 to 6, n = 2 to 20, and R is one or more different aliphatic or aromatic organic moieties having 1 to 20 carbon atoms, which may include one or more oxygen, sulfur, nitrogen, or fluorine atoms associated with the chain when R comprises an aliphatic chain. The linear chain may be linear or branched, saturated or unsaturated, and wherein either the aliphatic chain or the aromatic ring may have substituted groups thereon; and a barrier layer formed adjacent a surface of the solid lithium anode consisting of a reaction product of the solid lithium anode with the liquid organosulfur cathode.
