The conductivity of the pure CS/PEO SPE was 5.61 × 10 −8 S cm −1 and increased to 2.50 × 10 −6 S cm −1 in the sample SPE1. The conductivity of the SPE ions increased after the addition of NaClO 4 salt. The conductivity of the pure CS and PEO ions was the same. The ionic conductivity of the SPE increased after the addition of NaClO 4 salt. The ionic conductivity from the optimization of the NaClO 4 salt concentration is shown in Figure 1. The addition of FA (5 wt.%) increased the conductivity to 3.20 × 10 −4 S cm −1 at 30 ☌ and increased to 4.34 × 10 −3 S cm −1 at 60 ☌. SPE conductivity analysis using EIS showed the optimum results for SPE fabricated with a ratio of CS:PEO:NaClO 4 = 3:2:7.5, which was 1.02 × 10 −4 S cm −1 at 30 ☌ and increased to 2.13 × 10 −3 S cm −1 at 60 ☌. The SPE composite morphology and elemental distribution were investigated using SEM. The SPE characterization using XRD and DSC showed a decrease in crystallinity after the addition of NaClO 4 and FA. The interactions between CS, PEO, NaClO 4, and fly ash were observed using FTIR. In this study, polymer composites based on CS and PEO were developed with the addition of FA as a filler using the solution casting method. Fly ash (FA) has been studied to be used as a filler to increase the ionic conductivity of SPEs. However, SPEs based on CS/PEO composites have low conductivity. Chitosan (CS), an organic polymer, was blended with polyethylene oxide (PEO) to enhance its electrochemical properties. Solid polymer electrolytes (SPEs) have been successfully fabricated from CS/PEO/NaClO 4/Fly ash composite.
