In this research, a new system for electrical double-layer capacitors (EDLCs) is introduced that employs biopolymer blend electrolytes incorporating glycerol as a plasticizer. To prepare the films, the solution cast technique was employed to produce sodium-conducting plasticized chitosan:poly(oxazoline) (CH:POZ) systems. Sodium bromide (NaBr) salt was used as a sodium ion provider along with various concentrations of plasticizer to enhance the conduction mechanism. Using electrochemical impedance spectroscopy (EIS), the conductivity, diffusion coefficient, mobility, and number density of ions were determined via simulated EIS results. The results showed that the maximum conductivity of 8.27 x 10-4 S/cm was achieved when 45 wt.% of glycerol was added. The study also investigated the effect of plasticizers on the relaxation time for sodium conduction and the electrochemical behavior of the samples. The superior performance of the system was further confirmed by electrochemical measurements such as linear sweep voltammetry (LSV) and cyclic voltammetry (CV).
