An electrochemical investigation on polyvinylidene fluoride-based gel polymer electrolytes
Abstract Many types of polymer electrolytes have been developed and characterized in the past few years. Recently special attention has been focussed on the development of gel polymer electrolytes consisting of host polymers such as PAN, PVC, PVP, PVS, PMMA, PEGDA and PVdF etc., as they may find unique applications in consumer electronic and electric vehicle products. In the present study, gel polymer electrolytes have been prepared using the solvent casting technique in the presence of PVdF-1015 (SOLEF), EC+PC as a plasticizer, and LiBF 4 salt. The influence of the amount of polymer, plasticizer and LiBF 4 on the gel electrolytes has been studied using XRD, DSC, AC impedance and charge–discharge studies.
