Abstract

We prepare electrospun nanofibers (NFs) from a poly(N-vinylpyrrolidone)/ manganese (II) acetate composite by electrospinning for application in supercapacitors. As-spun hybrid NFs are calcined at different temperatures to remove the polymer matrix, resulting in inorganic MnO_x NFs of variable compositional ratios of Mn₃O₄ to Mn ₂O₃. Interestingly, the sample of MnO_x NFs that is calcined at 500 C exhibits the highest electrochemical performance, reaching a high specific capacitance of 360.7 F g^-1 at a current density of 1 A g^-1. This remarkable performance is attributed to the unique three-dimensional morphology and the reduced interfacial resistance of the mixed-phase MnO_x NFs within the matrix electrode and the electrolyte.
