Porous spherical MnCo₂S₄ was synthesized by a simple solvothermal method. Thanks to the well-designed bimetallic composition and the unique porous spherical structure, the MnCo₂S₄ electrode exhibited an exceptional specific capacitance of 190.8 mAh·g^-1 at 1 A·g^-1, greatly higher than the corresponding monometallic sulfides MnS (31.7 mAh·g^-1) and Co₃S₄ (86.7 mAh·g^-1). Impressively, the as assembled MnCo₂S₄||porous carbon (PC) hybrid supercapacitor (HSC), showed an outstanding energy density of 76.88 Wh·kg^-1 at a power density of 374.5 W·kg^-1, remarkable cyclic performance with a capacity retention of 86.8% after 10 000 charge-discharge cycles at 5 A·g^-1, and excellent Coulombic efficiency of 99.7%.
