Method of making an electrode for an electrochemical capacitor and the method of making an electrochemical capacitor

摘要

The present invention provides a method of making an electrochemical capacitor electrode comprising a collector and an electronically conductive porous layer formed on the collector while keeping an electric contact therewith. The porous layer contains at least a porous particle made of a carbon material having an electronic conductivity and a binder capable of binding the porous particle. The method comprises a plasma processing step of subjecting a material to high-frequency thermal plasma processing in a plasma gas atmosphere so as to yield the porous particle. All the manufacturing steps subsequent to the plasma processing step are carried out in an inert gas atmosphere.
