Manganese (Sulfide/Oxide) based electrode materials advancement in supercapattery devices

Recently, energy storage devices, specifically supercapattery devices, have attained much attention due to their high energy density (E), extraordinary power density (P) and high stability devices. Manganese (sulfide/oxide) based nanomaterials are more stimulating than conventional materials for supercapattery energy storage devices. They are due to their high conductivity, porous area and surface sensitivity, cost-effectiveness, simple fabrication, and less hazardous to the environment. This review describes a detailed study on manganese (sulfide/oxide) based electrode materials in energy storage devices. The synthesis methods of nanomaterials, such as hydrothermal, precipitation, chemical vapour deposition (CVD), electrodeposition, and energy storage mechanisms, are explained. Further, the composites of manganese (sulfides/oxide) based electrode materials with other materials are discussed to enhance the impact and performance of the host material. This review paper summarizes recent developments in sulfides/oxide-based electrode materials for supercapattery devices as viable next-generation high-performance batteries or supercapacitors replacement. In conclusion, future prospective and suggestions delivers a comprehensive thought and road map for the growth of future materials in energy storage devices.
