Mesoporous NiCo2O4 nanoneedles@MnO2 nanoparticles grown on nickel foam for electrode used in high-performance supercapacitors

Tuning electronic structure of δ-MnO2 by the alkali-ion (K, Na, Li) associated manganese vacancies for high-rate supercapacitors

“…As shown in Fig. 5, all samples displayed a type IV isotherm with a H3 hysteresis loop, which were the characteristic of mesoporous structure [47]. There was no obvious change in pore size distribution after introducing Mn vacancies (Fig.…”

Fabrication of resorcinol-based porous resin carbon material and its application in aqueous symmetric supercapacitors

“…The preparation methods of carbon materials with adjustable pore size and large specic surface area include chemical activation, physical activation, template method, polymer carbonization method and dealloying method. [18][19][20][21][22][23] Among the above methods, chemical activation method has comprehensive advantages, such as low cost, high efficiency, good preparation technology and one-step preparation of porous carbon with large specic surface area. Therefore, chemical activation method has been widely studied and applied.…”

Cost‐Effective Synthesis of Electrodeposited NiCo2O4 Nanosheets with Induced Oxygen Vacancies: A Highly Efficient Electrode Material for Hybrid Supercapacitors

“…Amongst these, NiCo 2 O 4 is of particular interest because of its high theoretical capacitance, superior electrochemical activity, and good electrical conductivity over the individual metal oxides [13−15] . To date, various synthesis routes have been employed like sol‐gel, [16] hydrothermal, [17] microwave, [18] template‐assisted, [19] and electrodeposition [20] for having different nanostructures of NiCo 2 O 4 such as nanotubes, [21] nanosheets, [22] nanowires, [23] nanoneedles, [24] etc. that contribute in various ways for increasing the capacitance owing to their inherently high active area available for redox reactions.…”
