Publication number: 20120088162Abstract: An ion transporting solvent for use with batteries can be improved by simultaneously shortening a phosphazene compound's pendent groups, eliminating most or all of the distal ion carriers, and randomizing the solvent molecules so as to intentionally disrupt symmetry to the maximum degree possible. The combination of these strategies dramatically improves battery performance to the point where the performance recorded is comparable to batteries using conventional organic solvents.Type: ApplicationFiled: May 13, 2011Publication date: April 12, 2012Inventors: Mason K. Harrup, Thomas A. Luther, John Leslie Burba
