Title:
METHOD FOR MANUFACTURING CARBON FIBER COATED WITH METAL CATALYST, AND CARBON FIBER FOR PRODUCTION OF ELECTRODE MANUFACTURED THEREBY
Document Type and Number:
WIPO Patent Application WO/2022/215809
Kind Code:
A1
Abstract:
The present invention comprises the steps of: preparing a precursor fiber including a carbon fiber precursor and an organic solvent; impregnating the precursor fiber in a coating solution containing a metal catalyst in the form of a metal ion or a ligand bound to a metal ion; coating the metal catalyst by heating and stretching the precursor fiber impregnated in the coating solution; and heat-treating the precursor fiber coated with the metal catalyst under an inert gas atmosphere. According to the present invention, as a metal catalyst in the form of a metal ion or in the form of a ligand bound to a metal ion is coated on the surface of a polymer carbon fiber, it is possible to manufacture the carbon fiber which is morphologically uniform and exhibits excellent mechanical and electrochemical properties.
