  • Method and apparatus for making electrodes for an ionic liquid-based supercapacitor, and method for making such a supercapacitor
    Patent number: 12142426
    Abstract: A method for making an electrode for an ionic liquid-based supercapacitor comprising two electrodes (anode, cathode) separated by an ionic polymer electrolyte separator, comprising: a step for making a carbon paste resulting from mixing carbon materials, ionic liquids and a binder, so as to obtain an active material for the electrode at room temperature, and a step for forming the electrode from mechanically processing the active material. A supercapacitor comprising a stack of a cathode electrode, an electrolyte separator and an anode electrode, the cathode and anode electrodes being electrically connected to current collectors, wherein the electrolyte separator comprises a polymer with an ionic liquid and the electrodes comprise a carbon-based active material mixed with an ionic liquid electrolyte and a binder.
