METHOD OF PRODUCING CURRENT COLLECTOR FOR ELECTROCHEMICAL ELEMENT, METHOD OF PRODUCING ELECTRODE FOR ELECTROCHEMICAL ELEMENT, CURRENT COLLECTOR FOR ELECTROCHEMICAL ELEMENT, ELECTROCHEMICAL ELEMENT, AND COATING LIQUID FOR FABRICATING CURRENT COLLECTOR FOR ELECTROCHEMICAL ELEMENT
Abstract:
An object of the present invention is to provide a method of producing a current collector for an electrochemical element that enable rapid charging and discharging with low internal resistance. The method of producing a current collector for an electrochemical element in the present invention has a step for coating a coating liquid onto a metal foil, the coating liquid containing at least one substance selected from the group consisting of methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxyethyl methyl cellulose, hydroxyethyl ethyl cellulose, hydroxypropyl methyl cellulose, hydroxyethyl starch, hydroxypropyl starch, dextrin, pullulan, dextran, guar gum and hydroxypropyl guar gum; an organic acid having valence of two or more or a derivative thereof, carbon particles and an organic solvent, followed by removing the organic solvent and forming a coating layer on the metal foil.
