Dielectric behaviours of peo-licf 3 so 3 electrolytes / Siti Zaubidah Abdullah

Polymer electrolyte composed of poly (ethylene oxide) as a host polymer and LiCF 3 SO 3 as salt was studied. Different compositions of PEO-LiCF 3 SO 3 electrolytes were prepared by solution casting technique. Measurement of conductivity and dielectric properties were carried out on these films as a...
