Lithium ion conducting solid polymer electrolytes (SPE) based on P(GMA-co-EMA)(80/20) doped LiClO4 as charge carrier was prepared by solution casting method. P(GMA-co-EMA) has been synthesized by photopolymerisation technique. Interactions between the polymer and salt were studied using fourier transforms infrared (FTIR). Ionic conductivity, electrochemical stability window, thermal and crystallinity behavior of polymer complexes were studied by AC impedance, cyclic voltammetry, and x-ray diffraction (XRD), respectively. Based on FTIR result, it was observed that the Li+ ions interacted with carbonyl group, the ether group and the epoxy oxygen of the GMA and EMA. The highest ionic conductivity of the electrolyte obtained at 2.8×10-5 S cm-1 at 25°C and 1.75×10-4 S cm-1 at 100°C. These solid polymer electrolytes showed electrochemical stability window up to 3.8 V. Furthermore, the thermal stability of the electrolyte increases with an increase in the salt content. These conductivity results were supported by XRD analysis which depicted that the semi-crystalline nature of P(GMA-co-EMA) was reduced to amorphous state due to an increase of LiClO4 content. The above results indicate that this material, namely PGMA- has potential for lithium ion application. © 2013 by ESG.
