AB - The present work is focused on the synthesis and detailed study of biopolymer phytagel and sodium thiocyanate (NaSCN)-blended polymer electrolyte films for supercapacitor applications. Here, the solution cast technique has been used to synthesize the biopolymer phytagel-based polymeric films with different concentrations of sodium thiocyanate. The prepared polymer electrolyte films are characterized for their structural, electrical, and dielectric properties using different characterization tools such as X-ray diffraction, Fourier transform infrared spectroscopy, electrochemical impedance spectroscopy, linear sweep voltammetry, and Wagner polarization technique. The film with 35wt% sodium thiocyanate shows a maximum conductivity of 6.36 × 10−4 S/cm. A laboratory scale symmetric supercapacitor device (EDLC) is fabricated using activated carbon as an electrode material and maximum conducting phytagel-based polymer electrolyte, which is further characterized using electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). The fabricated electric double-layer capacitor shows a specific capacitance of 38.65 F/g at a scan rate of 5 mV/s.
