Review on MnCo2S4-based composite materials for supercapacitors

Abstract

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.
