ELECTRODE, ELECTRIC DOUBLE-LAYER CAPACITOR USING SAID ELECTRODE, AND METHOD FOR MANUFACTURING SAID ELECTRODE

WIPO Patent Application WO/2014/192776

A1

This invention provides the following: an electrode comprising a mix of a carbon powder and fibrous carbon wherein the impact of a resin binder or the like is eliminated, the electrical resistance of said electrode is reduced, and said electrode exhibits superb capacity characteristics; an electric double-layer capacitor using said electrode; and a method for manufacturing said electrode. Said method has the one of following steps: a dispersion step in which fibrous carbon and a carbon powder having a grain diameter of less than 100 nm are dispersed in a solvent; or a dispersion step in which fibrous carbon and a carbon powder that has a grain diameter of at least 100 nm but less than 10 µm and has been treated so as to be made porous are dispersed in a solvent via either a process in which jets of a solution are made to collide with each other or a process in which shear stress and centrifugal force are applied to said solution. Said method also has an electrode formation step, after the dispersion step, in which a collector is coated with the solution resulting from the dispersion step, yielding a layer comprising a carbon-powder/fibrous-carbon mix.
