Abstract

Solid polymer electrolytes based on Polyethylene oxides (PEO's) and Lithium aluminate composites with mesoporous silica at different weight percentages were prepared using a solution casting technique. The morphology and complexity of the composite membrane were measured by SEM and FTIR. Electrical conductivities were measured in the temperature range of 303-373 K and conductivity was found to increase with the increase of dopant concentration as well as temperature. Because of the addition of I-/I3 -, the solid polymer electrolyte membrane could also be used in solar cells and super capacitors. The cycle voltammetry can also be used to study the influence of mesoporous silica on the capacitance of the membrane.
