ELECTRODE MATERIAL AND METHOD FOR PRODUCING SAME

摘要

Disclosed is an electrode material which secures both high capacitance and high long-term stability, while being improved in adhesion with conductive materials. Such an electrode material comprises an aluminum foil (1) and a carbon-containing layer (2) formed on the surface of the aluminum foil (1). An intervening layer (3) containing aluminum element and carbon element is formed between the aluminum foil (1) and the carbon-containing layer (2). Also disclosed is a method for producing an electrode material which comprises a step for placing an aluminum foil in a space containing a hydrocarbon-containing substance, and a step for heating the aluminum foil.
