Journal ArticleDOI
Charge Storage Mechanism of MnO2 Electrode Used in Aqueous Electrochemical Capacitor
TL;DR: The charge storage mechanism in MnO2 electrode, used in aqueous electrolyte, was investigated by cyclic voltammetry and X-ray photoelectron spectroscopy as discussed by the authors.
Journal ArticleDOI
Influence of Microstucture on the Charge Storage Properties of Chemically Synthesized Manganese Dioxide
TL;DR: In this paper, the α-MnO2 powder was synthesized by a simple coprecipitation technique and tested as active electrode material for an electrochemical supercapacitor, showing that an average capacitance of 166 F/g can be reproducibly obtained within a voltage range −0.4/+0.5 V vs Hg/Hg2SO4 using a sweep rate of 2 mV/s.
Journal ArticleDOI
Crystalline MnO2 as Possible Alternatives to Amorphous Compounds in Electrochemical Supercapacitors
Thierry Brousse,Thierry Brousse,Mathieu Toupin,Romain Dugas,Laurence Athouël,Olivier Crosnier,Daniel Bélanger +6 more
TL;DR: The capacitance of the crystallized materials is clearly dependent upon the crystalline structure, especially with the size of the tunnels able to provide limited cations intercalation as discussed by the authors.
Journal ArticleDOI
Nanostructured transition metal oxides for aqueous hybrid electrochemical supercapacitors
TL;DR: In this article, the authors present an overview of the research carried out in our laboratories with low-cost transition metal oxides (manganese dioxide, iron oxide and vanadium oxide) as active electrode materials for aqueous electrochemical supercapacitors.
