Chitosan (C) used as the source of carbon skeleton and N-dopant; Mn₃O₄@NC/CC electrodes were fabricated on carbon fiber cloth (CC) by hydrothermal technology to enhance the capacitive performance of the supercapacitor electrode. Introducing the special carbon skeleton, the specific surface area, micropore area fraction and pore volume of the as-prepared materials are increased, and the dispersion of Mn₃O₄ in carbonized chitosan is improved. The CV characterization demonstrated the relationship between the charge storage, current contribution ratio of the Mn₃O₄@NC/CC electrode with the addition amount of chitosan. As the weight fraction of chitosan increases, the capacitive behavior of the electrode exhibits a higher specific capacitance value and has a higher EDLC behavior. The as-fabricated Mn₃O₄@NC(2)/CC electrode has a specific capacity of 390.4 C g^-1 at 1 A g^-1 in 1 M Na₂SO₄ electrolyte and has an excellent capacity retention of 89.3% at 5000 cycling.
