Study of electrochemical performance of 3-D MnO2 nanoflowers coated with carbon for supercapacitors

A critical review on orthosilicate Li2MSiO4 (M = Fe, Mn) electrode materials for Li ion batteries

“…In GCD, the graph represents potential versus time period for each charge/discharge cycle at different value of current. GCD technique is used to evaluate battery parameters charge/discharge capacity, cyclic performance, energy density, coulombic efficiency, and capacity retention after 'n' cycles [154].…”

Polypyrrole and activated carbon enriched MnCo2O4 ternary composite as efficient electrode material for hybrid supercapacitors

“…They have attracted wide research interest due to their admirable electrochemical traits such as high storage ability, fast power delivery, extended cyclic life, wide temperature operating range, and safe operation. 9,10 However, SCs are still a long way from being widely used in real-world energy storage applications because their energy density is inferior to that of other energy storage systems (ESSs), such as fuel cells (∼350 W h kg −1 ) and LiBs (∼300 W h kg −1 ). This problem has stimulated creative modifications in creating advanced electrode materials for SCs.…”

Theoretical investigation of quantum capacitance of Co-doped α-MnO2 for supercapacitor applications using density functional theory

“…MnO 2 has pertinence among all other transition metal oxides since it possesses variable oxidation states, vast abundance, low cost, and excellent capacitance (B1370 F g À1 ) in aqueous electrolytes. 2,[12][13][14] Furthermore, its tunnel crystal structure can favor ion diffusion more than other spinel structures, which can facilitate redox processes. It is much cheaper and readily available.…”
