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

摘要

Disclosed is an electrode membrane composed of carbon particles and inorganic particles having a diameter within the range of 1-100 nm, wherein carbon particles are bound together by the inorganic particles. Also disclosed is an electrode comprising a collector and an electrode membrane arranged on the collector, wherein the electrode membrane is the above-described electrode membrane. This electrode can be produced by a method comprising a step for forming a dispersion film by applying a dispersion liquid, which contains carbon particles and inorganic particles having a diameter within the range of 1-100 nm dispersed in a liquid medium, over a collector and a step for forming an electrode membrane composed of the carbon particles and inorganic particles by removing the liquid medium from the dispersion film. Further disclosed is an electric double layer capacitor employing such an electrode.
