Role of various redox additive electrolytes on the electrochemical performances of mixed metal oxide loaded multiwalled carbon nanotube based supercapacitors

3D porous cementitious electrolytes with “stream-reservoir” ionic channels for high multifunctional performance structural supercapacitors

“…Most of the literature studies demonstrate that the addition of a redox additive in an active electrode material or electrolyte enhances the performance of the supercapacitor. [48][49][50] Fig. 6a exhibits the photograph of the C 14 BE-PCE-based redox-active SSC.…”

Fe Foam/Electroactivated Peroxydisulfate: A Highly Efficient Method to Remove Elemental Mercury

“…The electrolyte in the EA oxidation process is a significant factor for obtaining a high performance. As is well known, the charge between the anode and the cathode would transfer through the electrolyte, which acts as a medium of charge transport . Therefore, the selection of a suitable electrolyte is important in the process of electroactivation of PDS in Hg 0 removal for high performance.…”

Unleashing the Potential: Augmented Supercapacitor Performance of Bi2O3/MnO2@MWCNT Nanocomposites with Redox Additive Electrolyte

“…To improve the performances of these electrolytes, redoxactive materials were incorporated into the electrolyte, which provided additional electrochemical reactions within the electrolyte. 10,14,32,37 In this work, two different approaches were used to improve the conductivity and electrochemical performances of Bi 2 O 3 / MnO 2 (BM) nanocomposites (NCs) for SC applications. A MWCNT was hydrothermally incorporated with BM NCs (BMM NCs) to improve the overall conductivity of the BM NCs.…”

“…Typically, electrolytes, such as, the aqueous solutions containing inorganic salts (e.g., KOH, Na 2 SO 4 ), organic liquids, ionic liquids, polymer electrolytes, solid electrolytes, and so on, were used as the charge transfer agents in SCs. − However, the role of these electrolytes in electrochemical reactions was null. To improve the performances of these electrolytes, redox-active materials were incorporated into the electrolyte, which provided additional electrochemical reactions within the electrolyte. ,,, …”

“…Generally, reduced graphene oxide (rGO), graphene oxide, multiwalled carbon nanotubes (MWCNTs), and other carbon-based electrode materials provided excellent strength, conductivity, surface area, and moderate electrochemical properties. ,,, Moreover, the integration of MWCNTs in metal oxides/mixed metal oxides leads to enhanced electrochemical performances by the synergistic impact between the MWCNTs and metal oxides/mixed metal oxides. It originated from the amalgamation of the pseudocapacitive and electric double-layer capacitive (EDLC) behaviors of mixed metal oxides and carbonaceous materials, respectively.…”
