Manganese ferrite offers several advantages when employed as an electrocatalytic material for supercapacitors, including outstanding cycle stability and energy capacity. When compared to identical-metal sulfides, specific capacitance (Csp) of MnFe2O4 remains inadequate. So, using the hydrothermal synthesis technique, partial sulfur doping of MnFe2O4 was achieved to investigate the synergetic effect of oxides and sulfides. Various spectroscopic and microscopic studies demonstrate that adding sulfur atoms into MnFe2O4 increases the lattice parameters, which improves electrochemical performance. At a current density around 2 A g−1, then calculating MnFe2O4 with partial sulfur doping has a Csp of 1,201.60 F g−1, that is greater than 784.0 F g−1 of pure MnFe2O4. Maximum energy density (Ed) of 93.62 Wh kg−1 was produced with a power density (Pd) of 749 W kg−1. The current study depicts that partial sulfur doping can enhance the electrochemical behavior of MnFe2O4. As a result, the present work shows more effective in field of energy storage by enhancing their poor electrochemical performance.
