Ternary spinel MnCo2S4 spherical nanoparticles are prepared through a simple one step hydrothermal approach with precursors followed by an ion exchange reaction. The obtained spherical nanoparticles offers a high specific surface area with mesoporous structure, this aids in providing outstanding electrochemical performance with a specific capacitance of 707.77 F/g at 2 A/g and a good cyclic stability (initial capacitance of 95.15% after 10000 cycles). It offers a high energy density of 78.17 W h Kg−1 to satisfy the commercial needs. By the utilization of structural and electrochemical benefits, MnCo2S4 electrode establishes its significant potential in the field of energy storage system.
