Conclusion
MXene, a novel conducting nanofiller, has been effectively employed as a plasticizer with additive material for conductivity enhancement in ion-conducting electrolyte polymer films composed of polyethylene oxide and sodium iodide using the conventional solution casting procedure. The amendment the surface morphology of polymeric electrolyte sheets has changed after being doped with various weight percentages of this novel nanofiller, as demonstrated by POM. This shows that the amorphous phase in the polymer electrolyte system has increased as well as the overall amorphousness of the polymer electrolyte material. But a 0.04 weight percent nanofiller doped polymer electrolyte film has been proven to be stable at 400 C. After nanofiller was added to the polymer matrix, there was an increase in ionic conductivity, and the composition with 0.04 wt% nanofiller had the highest value of ionic conductivity (2.05 x 10-4 S/cm). The EDLC cell was constructed using an optimized polymer MXene doped electrolyte film. The specific capacitance Csp signifies calculated from the cyclic voltammetry curve along with impedance data were 186 F/g and 190 F/g, respectively. Considering the optimised ion-conducting polymer electrolyte, the ionic transference number of mobile species for the improved ion-conducting polymer electrolyte was determined to be 0.92, confirming that the system is primarily ionic in nature.
