synthesis of polyvinylidene fluoride/polythiophene as gel polymer electrolytes for lithium-ion batteries

Polymer-based lithium-ion batteries have drawn a lot of attention due to their potential to produce systems that are inherently safe and more flexible. in recent years, novel polymer matrices via macromolecular design with multiple functional groups have been proposed for polymer electrolyte preparation. in this work, polythiophene (pt) as conductive material was synthesized by the cationic polymerization method. the gel polymer electrolyte (gpe) of polyvinylidene fluoride-polythiophene pvdf/pt blend in different ratios of pvdf to pt (10 to 50 % wt) prepared by solution casting technique. then, the electrolyte properties were characterized by the eis test. the result showed that ionic conductivity was improved by increasing the pt ratio in the blend.
