This project were conducted in order to understand and observed the electrical properties of MG-49. This present research aims to use poly (methyl-methacrylate)-grafted natural rubber (MG49) as the polymer host. This polymer host will provide medium for ion transport. This present research aims to replace lithium ion salt and uses ammonium triflate (NH4CF3SO3) as the dopant salt. After investigation has been carried out, the conductivity was found to increase with addition of certain weight percentage of MG-49. The highest ionic conductivity of the electrolyte was 3.28x10-2 S cm-1 with addition of 11% of weight percentage of MG-49. Other than that, with the used of zinc and polypyrrole in the battery, the highest specific capacity obtained at the first cycle was 7.0 mAhg-1 .
