Preparation, Characterizations and Conductivity of PEO-PMMA Based Polymer Blend Electrolyte for Lithium Ion Battery

Abstract

In the present work we have prepared a polymer blend electrolyte comprising of poly (ethylene oxide) PEO, poly (methyl methacrylate) PMMA and LiClO4 as filler. The polymer blend electrolyte was developed as a film by solution casting technique, with varying ratio of the filler. X-ray diffraction (XRD) revealed that the incorporation of LiClO4 ions into the blend suppresses the crystallinity of PEO. The SEM studies showed that the particles are spherical, ranging in size from 35-95μm .The ionic conductivity was maximum for 5 wt% of the blend at the ambient temperature.
