Beschreibung
Zusammenfassung:	Disclosed are an electrolyte solute and an electrolyte for a high-voltage super-capacitor, and a high-voltage super-capacitor utilizing the electrolyte. Anions of the electrolyte solute can be selected from one or more of tetrafluoroborate, hexafluorophosphate, bis(trifluoromethanesulphonyl) imide, bis( trifluoromethanesulphonyl) methyl and perfluoroalkyl sulfonate, and cations can be selected from one or more of N-methyl-1,4-diazabicyclo[2.2.2] octane ammonium, N,N-dimethyl-1,4-diazabicyclo[2.2.2] octane ammonium and N-methyl-1-azabicyclo[2.2.2] octane ammonium. The high-voltage super-capacitor can operate stably for a long time at a voltage of 2.7V-3.2V, thus improving the energy density, maintaining the high power density characteristic and also prolonging the service life.
