Title (EN) AN IMPROVED METHOD FOR PREPARING AQUEOUS MNO2 INK AND CAPACITIVE ENERGY STORAGE
(FR) PROCÉDÉ AMÉLIORÉ DE PRÉPARATION D’ENCRE AQUEUSE MNO2 ET STOCKAGE CAPACITIF D’ÉNERGIE
Abstract: front page image
(EN)A method of preparing manganese dioxide(MnO 2) ink comprises mixing potassium permanganate(KMnO 4) solution with highly crystalline carbon particles(HCCPs) with average diameters less than 800 nm at 30-60℃ for at least 8 hours. Also provided are symmetric supercapacitor device comprising MnO 2coated electrodes and solid state ionic liquid as electrolyte, as well as interdigital transparent supercapacitor device comprising aqueous MnO 2 ink.
(FR)La présente invention décrit un procédé de préparation d’une encre à base de dioxyde de manganèse (MnO2) comprenant le mélange d’une solution de permanganate de potassium (KMnO4) avec des particules de carbone fortement cristallines présentant des diamètres moyens inférieurs à 800 nm à 30 à 60 °C durant au moins 8 heures. Sont également décrits un dispositif supercondensateur symétrique comprenant des électrodes revêtues de MnO2 et un liquide ionique à l’état solide comme électrolyte, ainsi qu’un dispositif supercondensateur transparent interdigité comprenant de l’encre aqueuse MnO2.
