Title: Inorganic electrolyte solutions and gels for rechargable lithium batteries

Abstract

A class of inorganic oxychloride compounds have been evaluated for use as electrolytic solvents in rechargeable lithium batteries. Compared with SO{sub 2}-based electrolytes, these showed much improved safety while maintaining room temperature conductivities of 10{sup {minus}3}--10{sup {minus}2} S/cm and electrochemical voltage windows of 4.5--5.5 vs. Li{sup +}/Li and supporting reversible lithium metal deposition/stripping. With the addition of 2 {approximately} 5% polymer, the solutions acquire rubbery character with little loss of conductivity and no change in electrochemical stability. Preliminary charge/discharge tests with intercalation-type cathode as well as sulfur-based cathode showed that these inorganic electrolytes can operate with excellent reversibility.
