Ionic Melt Electroltyes for Lithium Battery Applictions

Ionic melt electrolytes consisting of lithium salts of fluorosulfonamide anions covalently attached to oligomeric polyether chains were synthesized and characterized with respect to structure and ion transport characteristics. Conductivity data are reported for melts of variable ether- oxygen-to-lithium ratio, and for melts having different amounts of polyether plasticizers added. Conductivities are generally high relative to true polymer electrolytes.
