ELECTRODE MEMBRANE, ELECTRODE AND METHOD FOR PRODUCING THE SAME, AND ELECTRIC DOUBLE LAYER CAPACITOR

摘要

An electrode film is provided which comprises carbon particles and inorganic particles having a particle diameter within the range of from 1 nm to 100 nm, wherein the carbon particles are bound together by the inorganic particles. In addition, an electrode is provided which has a current collector and an electrode film disposed on the current collector, wherein the electrode film is the aforesaid electrode film. This electrode can be produced by a method which has applying a dispersion liquid containing carbon particles and inorganic particles having a particle diameter within the range of from 1 nm to 100 nm dispersed in a liquid medium, to a current collector to form a dispersion liquid film, and removing the liquid medium from the dispersion liquid film to form an electrode film composed of the carbon particles and the inorganic particles. Furthermore, an electric double layer capacitor in which the aforesaid electrode has been incorporated is provided.
