Abstract
In the present study, Zn2+-ion-conducting polymer electrolyte (PE) films were synthesized using PVDF-co-HFP, PEO, Zinc Trifluoromethanesulfonate, and addition of ionic liquid. The film exhibited high ionic conductivity (σrt~ 3.20 × 10–4S·cm−1) at room temperature, low activation energy (Ea~ 0.21 eV), and a high ionic transference number (tion~ 0.99). Electrochemical property studies including cyclic voltammetry, open circuit potential, and charge–discharge analysis were performed for the fabricated cells with the synthesized PEs, Zn and V2O5-based electrodes. The cell achieved a maximum specific capacitance of 46.43 F·g−1. X-ray Diffraction, FESEM and DSC analyses supported the observed electrical and electrochemical behavior. These results various confirm the suitability of ionic liquid-incorporated PE films for hybrid supercapacitor applications.Graphical abstract
