Abstract

In this study, ENR-50 based polymer electrolytes containing different concentrations of lithium triflate (LiCFaSCb) were prepared by the solution casting technique. An impedance investigation was conducted to determine the electrical conductivity of each sample. The conductivity was calculated using bulk resistance value in the frequency range between 100 Hz and 1 MHz at various temperatures ranging from 303 K to 383 K. The highest conductivity at room temperature for the sample containing 1 g ENR doped with 35 wt % UCF3SO3 was 1.98xl0"5 Scm'1 and its activation energy was 0.099 eV. Upon addition of 20 wt. %-EC as a plasticizer, the plasticized salted sample exhibited the highest electrical conductivity of 2.41x10"4 Scm"1. The highest conducting of the plasticized sample would then be used as a gelled electrolyte for fabrication of lithium - air cell. The capacity of the fabricated lithium - air primary cell was 1098 mAh/g.
