Solid polymer electrolytes (SPEs) play a pivotal role in advancing electrochemical devices, such as proton batteries and supercapacitors, owing to their potential for enhancing safety and flexibility. In this work, employs a solution casting technique to prepare SPEs, utilizing chitosan-dextran blends as the polymer matrix. Ammonium thiocyanate (NH4SCN) is incorporated as a charge carrier, while honey is introduced as a plasticizer. The interaction between these materials is confirmed through Fourier transform infrared (FTIR) analysis. X-ray diffraction (XRD) analysis reveals that the addition of 10 wt.% honey (H10) to the polymer blend results in the lowest degree of crystallinity (15.24%), emphasizing the pivotal role of plasticizers in modulating the structural properties of SPEs. Furthermore, by incorporating 40 wt.% NH4SCN (SN40) into the plasticizer-polymer host (H10), the ambient temperature conductivity obtains its maximum value of (1.08 +/- 0.19 x 10-3 S cm-1) with the lowest degree of crystallinity of 10.44%, verify it is the most amorphous electrolyte. The observed trend in conductivity is influenced by the diffusion coefficient (D), ion density (n), and mobility of the ions (mu). Complementing these findings, field emission scanning electron microscopy (FESEM) is employed to investigate the surface morphology and cross section of the SPEs, providing a comprehensive understanding of their structural characteristics. From linear sweep voltammetry (LSV), SN40 is electrochemically stable up to 2.2 V and the tion is 0.97 indicating that the ions are the dominant charge carriers.
