Fabrication of Ni-Plaque-Based Manganese Dioxide Electrodes for Electrochemical Supercapacitors

Electrodeposition of polypyrrole–carbon nanotube composites for electrochemical supercapacitors

“…The improved impregnation of the Ni plaques in the pulse method and remaining open porosity of the electrode resulted in better electrochemical performance. It is in this regard that pulse impregnation method [29] allowed more efficient impregnation of Ni plaques with MnO 2 and provided higher SC, compared to the galvanostatic impregnation method. The PPYeMWCNT loading achieved in this investigation was comparable with loading of MnO 2 reported in the previous investigation [29].…”

The PPYeMWCNT loading achieved in this investigation was comparable with loading of MnO 2 reported in the previous investigation [29]. Recent studies highlighted the importance of volume loading of porous current collectors with active material [28].…”

“…This problem can be addressed by the use of special current collectors, such as Ni foams or plaques. Previous investigations showed that Ni plaques [29], designed for high power applications, allowed significantly higher SC of MnO 2 electrodes, compared to MnO 2 electrodes based on Ni foams [30]. The advantages of Ni plaque based electrodes were especially evident at high chargeedischarge rates.…”

Performance of Solid-state Hybrid Energy-storage Device using Reduced Graphene-oxide Anchored Sol-gel Derived Ni/NiO Nanocomposite

“… 2 – 4 , while the pseudocapacitance is usually shown by metal oxides, hydroxides, and some redox polymers 5 , 6 . The ruthenium oxide (RuO 2 ) has been exploited as an electrode material for pseudocapacitor, besides other metal oxides such as MoO 3 , V 2 O 5 , Bi 2 WO 6 7 – 11 . However, due to the high cost of Ru, there is an urgent need for developing cheaper materials.…”

Effect of ball milling on capacitance of electrochemical double layer capacitor

“…The variety of aspect of this device has been considered by them [12], [13]. The various parameters of the electrochemical double layer capacitor like type of electrolyte, specific surface area, electrode material porosity, quantity of material deposited on electrode etc have been taken as input [14], [15].…”
