Preparation and Characterization of 49% Poly(Methyl Methacrylate) Grafted Natural Rubber (MG49)-Stannum (IV) Oxide (Sn02)-Lithium Salt Based Composite Polymer Electrolyte

49% poly(methyl methacrylate) grafted natural rubber (MG49) in the presence of 4% wt. stannum (IV) oxide (Sn02) and lithium salts (lithium tetrafluoroborate, LiBF4 and lithium perchlorate, LiCl04) in composite polymer electrolyte (CPE) films has been prepared. The MG49-Sn02 polymer electrolyte films...
