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.
