Interconnected plate-like NiCo2O4 microstructures for supercapacitor application

Nanorod-like Bimetallic Oxide for Enhancing the Performance of Supercapacitor Electrodes

“…Numerous studies have been conducted on NiMoO 4 because it is abundant in the Earth’s crust . Meanwhile, the particle size and shape, crystallinity, crystal structure, and porosity greatly influence NiMoO 4 electrochemical performance. − , Despite this, NiMoO 4 ’s limited electrochemical active surface area makes its electrochemical performance unsatisfactory . Hence, it is crucial to utilize an economical and simple fabrication technique to generate a structure with ample active surface area, thereby boosting the efficiency of NiMoO 4 …”

Electrochemical capacitance properties of pre-sodiated manganese oxide for aqueous Na-ion supercapacitors

“… 26 Recently, Yewale et al synthesized plate-like NiCo 2 O 4 by a hydrothermal method, which exhibited a SC of 550 F g −1 . 27 Also, there is growing interest on transition metal sulfides such as CuCo 2 S 4 , Co 3 S 4 , NiCo 2 S 4 etc. , because of their high specific capacitance values.…”

“…[14][15][16][17] However, low-cost and environment-friendly metal oxides such as MnO 2 , NiO, Ni(OH) 2 , NiCo 2 O 4 are widely studied as alternatives to toxic and costly RuO 2 . [18][19][20][21][22][23][24][25][26][27] For example, Munawar et al synthesized ower-like NiO by a surfactant-assisted method, which exhibited a SC of 397 F g −1 at a specic current of 1 A g −1 . 26 Recently, Yewale et al synthesized plate-like NiCo 2 O 4 by a hydrothermal method, which exhibited a SC of 550 F g −1 .…”

Performance degradation study of NiCo2O4-based asymmetric supercapacitors

“…In recent years, pseudocapacitors have been widely studied because of their higher energy density compared with double-layer capacitors. [6][7][8][9][10][11] The main application value of supercapacitors is their high power characteristics, but they also need a high enough energy density to store more energy for output. Transition metal oxides are one of the main electrode materials for pseudocapacitors, which can be stored by reversible redox reactions on or near the surface of active materials.…”
