ABSTRACT:
A method of manufacturing a supercapacitor electrode containing a metal oxide and carbon-containing material, the method including the following steps: starting from a salt of said metal dissolved in an aqueous solution of a strong base, the hydroxide of the metal is precipitated in the form of a gel by adding an alcohol; the precipitate of the hydroxide of the metal is washed and dried; active carbon is added to the precipitated hydroxide of the metal to consitute a first mixture; the first mixture is subject to heat treatment in order to transform the hydroxide into an oxide, and a mixture of metal oxide and of active carbon is obtained which constitutes the active material of the electrode; and a binder is added to the active material to form a paste which is put into the form of an electrode.
