Abstract

See full text

Provided are an electrode formed by mixing carbon powder and a fibrous carbon, wherein influence of a resin-based binder or the like and an conductivity promoting material or the like is eliminated to have low electric resistance and an excellent property of capacitance; an electric double-layer capacitor using the electrodes; and a manufacturing method of the electrode. Provided is a dispersion step in which the carbon powder with a particle size of less than 100 nm and the fibrous carbon are dispersed into a solvent. The dispersion step is to allow jets of the solution to collide with each other or to apply shear stress and centrifugal force to the solution, thereby dispersing the carbon powder and the fibrous carbon. Furthermore, the method comprises the sheet electrode forming step in which the solution subjected to the dispersion step is filtered to obtain the carbon powder/fibrous carbon sheet.
