Electrodeposited nanoflakes like hydrophilic Co 3 O 4 as a supercapacitor electrode

Enhancing pseudocapacitive properties of cobalt oxide hierarchical nanostructures via iron doping

“…At a scan rate of 5 mV/s, the Co 3 O 4 electrode only displays a high specific capacitance value of 393.6 F/g. These values are comparable with literature-reported values [ 40 ]. However, 0.25 M Fe-doped Co 3 O 4 nanoparticles electrodes exhibits a high Specific Capacitance value of 588.5 F/g at a scan rate of 5 mV/s ( Table 5 ).…”

Ag doped Co3O4 nanoparticles for high-performance supercapacitor application

“…9 ). It can be seen that specific capacities of 0.25 M Ag Co 3 O 4 NPs were higher than from recently reported results ( Table 4 [ 35 , [58] , [59] , [60] , [61] , 81 , [90] , [91] , [92] , [93] , [94] , [95] , [96] , [97] , [98] , [99] ]) [ 59 ]. As a result at slow scanning rate, the movement of ions around the inner and outer surfaces of the prepared nanostructured materials, which makes it possible to obtain a high specific capacity [ 100 ].…”
