Abstract
Przedmiotem wynalazku jest hybrydowy kondensator elektrochemiczny sodowo - jonowy, składający się z ujemnej elektrody węglowej, wykonanej z węgla aktywowanego o wysoce rozwiniętej powierzchni właściwej, zawierającej dodatek środka wiążącego oraz środka poprawiającego przewodnictwo, oddzielonej separatorem od elektrody dodatniej, gdzie elektrody umieszczone są w elektrolicie, charakteryzujący się tym, że elektrody usytuowane są w elektrolicie organicznym, stanowiącym roztwór o stężeniu 1 mol/dm3 chloranu (VII) sodu rozpuszczonego w 4-metylo-1,3-dioksolano-4-onie, a składnikiem aktywnym elektrody dodatniej jest tlenek manganu-sodu o wzorze sumarycznym NaxMnO2, gdzie x wynosi 0,4 do 0,67, korzystnie 0,4, przy czym elektroda dodatnia zawiera 70% tlenku manganu - sodu, 10% kopolimeru fluorowinylidenu i heksafluoropropylenu, 10% sadzy acetylenowej oraz 10% drugiego środka poprawiającego przewodnictwo elektronowe, zaś elektroda ujemna zawiera 10% wagowych karboksymetylocelulozy, jako środka wiążącego oraz 10% wagowych sadzy acetylenowej, jako środka poprawiającego przewodnictwo. Korzystnym jest, gdy drugim środkiem poprawiającym przewodnictwo elektronowe w elektrodzie dodatniej jest grafit lub grafit ekspandowany lub wielościenne nanorurki węglowe, korzystnie wielościenne nanorurki węglowe.The subject of the invention is a sodium-ion hybrid electrochemical capacitor, consisting of a negative carbon electrode made of activated carbon with a highly developed specific surface, containing the addition of a binding agent and a conductivity improving agent, separated by a separator from the positive electrode, where the electrodes are located in the electrolyte, characterizing due to the fact that the electrodes are located in an organic electrolyte, which is a solution with a concentration of 1 mol / dm3 of sodium chlorate dissolved in 4-methyl-1,3-dioxolane-4-one, and the active component of the positive electrode is manganese-sodium oxide with the summary formula NaxMnO2, where x is 0.4 to 0.67, preferably 0.4, wherein the positive electrode contains 70% manganese oxide sodium, 10% copolymer fluorovinylidene and hexafluoropropylene, 10% acetylene carbon and 10% second improving agent electronic conductivity and the negative electrode contains 10% by weight carboxym ethyl cellulose as a binder and 10% by weight of acetylene carbon as a conductivity enhancer. Preferably, the second agent for improving the electron conductivity in the positive electrode is graphite or expanded graphite or multi-wall carbon nanotubes, preferably multi-wall carbon nanotubes.
