Title: METHOD OF REDUCING OUTGASSING IN A SUPERCAPACITOR
Abstract:
A method of reducing outgassing in a supercapacitor comprised of carbon-containing electrodes and at least one ionic liquid is characterised by the steps of (a) contacting the carbon-containing electrodes with a tetrafluoroborate salt; (b) applying a potential difference across the carbon- containing electrodes whilst in contact with the salt in a cycle during which electrical charge is stored on and discharged from the electrodes; and (c) continuing further cycles of step (b) until such time as substantially no further outgassing from the system occurs.
