Manganese dioxide (MnO2) has been widely used in the field of energy storage due to its high specific capacitance, low cost, natural abundance, and being environmentally friendly. However, suffering from poor electrical conductivity and high dissolvability, the performance of MnO2 can no longer meet the needs of rapidly growing technological development, especially for the application as electrode material in metal‐ion batteries and supercapacitors. In this review, recent studies on the development of binary or multiple MnO2‐based composites with conductive components for energy storage are summarized. Firstly, general preparing methods for MnO2‐based composites are introduced. Subsequently, the binary and multiple MnO2‐based composites with carbon, conducting polymer, and other conductive materials are discussed respectively. The improvement in their performance is summarized as well. Finally, perspectives on the practical applications of MnO2‐based composites are presented.

“…Compared to other literature, we have 1) synthesised a novel α-MnO 2 -expanded graphite-PVDF composite, 2) the synthesis method was facile, low cost, and high yield, 3) very low contact resistance was observed upon the modification of FTO substrate with the composite material, 4) constancy in the shape of cyclic voltammogram suggested the rate capability and capacitive behaviour of the electrode, and finally, 5) the proposed cathode material demonstrated superior capacitance over other MnO 2 electrode based on FTO substrate [73][74][75][76][77].…”

A facile chemical reduction method is employed for the synthesis of α-MnO2 followed by ultrasonication with synthetic graphite and poly (vinylidene pyrrolidone) PVDF for the development of α-MnO2-expanded graphite-PVDF (MGP) composite. Known masses of MGP composite are drop-casted on a fluorine-doped tin oxide (FTO) conducting glass substrate for the fabrication of composite electrodes to use as the cathode. The compositional effects of various weight percentages of graphite on the electrochemical performance of the MGP composite are studied. The increase in graphite’s weight percentage is always accompanied by an equal reduction in the weight of MnO2 by maintaining a constant amount of PVDF. We demonstrate a maximum electrochemical performance for the composite containing 80% MnO2, 10% expanded graphite, and 10% PVDF, further increases in graphite concentration (reduction in that of MnO2) have detrimental effects on the performance. The basis characterisation of the composite is carried out using XRD, FTIR, UV-VIS, AFM, and SEM and the electrochemical studies are done using CV, GCD and EIS. We observe both faradaic and non-faradaic charge storage mechanisms in the composite samples with a 35% capacitive contribution and a 65% diffusive contribution to the total capacitance. Moreover, the composite electrode demonstrates a maximum specific capacitance of 358 F/g at 10 mV/s with an outstanding power density of 2.8 KW/Kg.

Enhancing the efficiencies of electrochemical reactions for converting renewable energy into clean chemical fuels as well as generating clean energy is critical to achieving carbon neutrality. However, this enhancement can be achieved using materials that are not constrained by resource limitations and those that can be converted into devices in a scalable manner, preferably for industrial applications. This review explores the applications of electrochemically deposited manganese dioxides (MnO2) and their composites as electrochemical catalysts for oxygen evolution (OER) and hydrogen evolution reactions for converting renewable energy into chemical fuels. It also explores their applications as electrochemical catalysts for oxygen reduction reaction (ORR) and bifunctional OER/ORR for the efficient operation of fuel cells and metal–air batteries, respectively. Manganese is the second most abundant transition metal in the Earth’s crust, and electrodeposition represents a binder‐free and scalable technique for fabricating devices (electrodes). To propose an improved catalyst design, the studies on the electrodeposition mechanism of MnO2 as well as the fabrication techniques for MnO2‐based nanocomposites accumulated in the development of electrodes for supercapacitors are also included in this review.
