HYBRID ELECTRODE FOR A SUPERCAPACITOR

摘要

The invention relates to an electrode for a supercapacitor and its manufacturing process. The electrode comprises an electrically conductive first material and a macromolecular material. The macromolecular material is grafted onto the first material; said macromolecular material generates a graphitic structure by pyrolysis, thereby increasing the specific surface area of the electrodes. The first material is a metallic foam made of silver or gold or based on carbon.
