Polymer electrolytes consisting of poly(ethylene oxide) (PEO) and lithium salts, such as LiCF 3 SO 3 and LiBF 4 are prepared by the ball-milling method. This is performed at various times (2, 4, 8, 12h) with ball:sample ratio of 400:1. The electrochemical and thermal characteristics of the electrolytes are evaluated. The structure and morphology of PEO-LiX polymer electrolyte...
