Abstract (en)
[origin: CA3180225A1] Disclosed is a method for selectively separating a carbon-containing material from a mixture comprising a positive electrode and a negative electrode originating from fuel cells and/or electrochemical batteries, the method comprising the following successive steps: a) providing a mixture comprising a positive electrode and a negative electrode, each electrode comprising a current collector, an active material and a binder, the active material of the negative electrode being a carbon-containing material, preferably graphite, b) bringing the mixture comprising the positive electrode and the negative electrode into contact with a separating solution, in the presence of ultrasound, the separating solution comprising a solvent and possibly additives, until the carbon-containing material is selectively separated from the current collector of the negative electrode, the active material of the positive electrode remaining joined to the current collector of the positive electrode.
