Are nickel-based materials supercapacitor-type materials?
The terminology of “supercapattery” is even used in some reports , . Hundreds of papers related to the nickel-based materials consider them as supercapacitor-type materials. Noteworthy, it is still under debate on the capacitive behavior of nickel-based materials.
Is nickel oxide a suitable electrode material for supercapacitors?
Nickel/cobalt oxides materials The nickel oxide has been considered alternative electrode materials for supercapacitors because of its facile to synthesize various morphologies, environmentally benign nature and low costs [62, 63].
What are nickel-aluminum-based supercapacitors?
Nickel-aluminum-based supercapacitors are primarily NiAl-layered double hydroxide. Layered double hydroxides (LDH), with the general formula of [M II1−x M IIIx (OH) 2] x+ [A n−] x/n and generally surrounded by hydroxyls, where M II and M III are divalent and trivalent cations and A is inorganic or organic anion, have grasped great attention.
Which carbonaceous materials are used in supercapacitors?
Among various carbonaceous materials, the activated carbons are the first and most widely applied for supercapacitors, owing to their very high specific surface areas and their accessible raw materials (which can be easily obtained from petroleum by-products and biomass etc.) with low price.
Are nickel/cobalt based materials for supercapacitors battery-type?
