This research is about the preparation of polymer blend electrolytes based on chitosan using solution cast technique. Field emission scanning electron microscopy and Fourier transform infrared spectroscopy (FTIR) routes were utilized for studying morphological and structural properties, respectively. Electrical impedance spectroscopy (EIS) was engaged for determining the direct current electrical conductivity of the films. The ion association at the highest salt concentration was actually present as confirmed by EIS and FTIR achievements. The sample surface displays the protrude salts at the highest salt concentration. Proton conducting polymer electrolyte with NH4Br as H+(proton) provider has been used in electric double-layer capacitor (EDLC) applications. The highest conducting sample was used to fabricate EDLC. The transference number measurement indicated that the sample is mostly includes ion charge carriers which are vital for application in electrochemical devices. The linear sweep voltammetry study revealed that the decomposition of the sample takes place above 1.54 V. The fabricated EDLC device was performed capacitive behavior, as it can be seen from the cyclic voltammetry (CV) plot. Since no redox peaks have appeared, it can be concluded that the EDLC did not undergo either oxidation or reduction. The acquired value of specific capacitance (132.5 Fg(-1)) is considered to be of great interest from the application viewpoints.
