Review on MnCo2S4-based composite materials for supercapacitors

Manganese-cobalt sulfide (MnCo2S4) based materials have shown immense potential in the field of energy storage which can be attributed to the high theoretical capacitance, cost-effectiveness, abundance, and feasibility in the synthesis. The present review is mainly classified into two categories of electrode materials: the pristine MnCo2S4 and the composites of MnCo2S4. Over the years, there have been numerous reports on this topic also comprised different experimentations. This report mainly reviews the advances that have taken place over time in MnCo2S4-based electrode materials alongside studying the effects of the morphology and the constituents of MnCo2S4. Moreover, the MnCo2S4 composites show higher performances than the pristine MnCo2S4, including a higher delivery of capacitance, energy density, and power density. Although the interest in this topic is constantly increasing, there is ample scope for the development of MnCo2S4-based materials on a large scale. The review also provides the current shortcomings in our observation and the possible solutions to overcome them.
