Abstract
A method of creating a composite cathode for use within a lithium ion battery. The method beginning with the step of preparing an electrolytic solution. The electrolytic solution includes a plasticizer, a crosslinkable polyether, a first lithium salt and a second lithium salt. The method ending with the step of impregnating a cathodic material with the electrolytic solution so as to form the composite cathode.
