One-pot synthesis of pearl-chain-like manganese dioxide-decorated titanium grids as advanced binder-free supercapacitors electrodes

“…It is well-known that there are various candidates for commonly known current collectors with individual constituents and good electricity, such as gold networks, copper foam, Ni-Fe foam, and carbon cloth [13][14][15][16][17][18]. Among these compounds, considerable research has been focused on titanium current collectors including Ti grids, foams and foils due to their good biocompatibility, excellent anti-corrosion and conductivity [19][20][21], so as to clarify the actual values of electrochemical properties for all the active materials.…”

One-pot electrodeposition synthesis of ZnO/graphene composite and its use as binder-free electrode for supercapacitor

“…[1][2][3] Considering their mode of charge-storage mechanisms, supercapacitors are generally categorized into two main types: (1) electrical double-layer capacitors (EDLCs), which store energy through the accumulated charge at the interface between an electrode and electrolyte; [4][5][6] (2) redox electrochemical capacitors or pseudocapacitors, where capacitance comes from reversible Faradaic reactions. [7][8][9] Presently carbonaceous materials are commonly investigated nanomaterials used in EDLCs, such as activated carbon, [10] carbon nanotubes, [11] carbon aerogels [12] and hybrid carbon. [6] As a rising star, graphene, a two-dimensional single-layer sheet of sp2-hybridized conjugated carbon atoms, has become the subject of intensive investigation in various research fields, such as energy storage, [13] solar cells, [14] and electrochemical sensors, [15][16][17] due to its excellent intrinsic electrical conductivity, extremely large specific surface area, extraordinarily superior chemical, environmental and mechanical stability.…”

“…[18] Therefore, the pseudocapactive materials are being explored for fabrication supercapacitors to improve the energy density since pseudocapacitors store and deliver energy through redox reaction, resulting in high specific capacitance. [19] Transition metal oxides such as MnO2, [20] NiO, [21] Co3O4, [7] are generally recognized as ones of the most promising candidates for pseudocapacitor electrodes.…”

Facile synthesis of Co3O4 with different morphology and their application in supercapacitors

“…Thus, various morphology of Co 3 O 4 has been reported, such as nanoparticles 14 , nanosheets 15 , nanowires 16 , nanotubes 17 and nanoflowers 18 etc. It has been found that Co 3 O 4 based pseudocapacitors mainly depends on properties such as surface area, morphology, and specific orientation of different facets.…”
