Graphite felt having multimodal porous carbon coating layer and redox flow battery using the same as electrodes

摘要

The present invention relates to graphite felt coated with multimodal porous carbon and a redox flow battery using the same as an electrode, and more specifically, to a method of manufacturing graphite felt having a multimodal porous carbon coating layer, an electrode for a redox flow battery using the same and a redox flow battery including the same as an electrode. The method includes a polymer solution preparation step of dissolving inherent microporous polymer in a good solvent; a polymer solution coating step of coating graphite felt with the polymer solution; a porous structural layer forming step of forming a porous structural layer on a surface of the graphite felt coated with the polymer solution through a phase transition scheme; and a carbonization step of carbonizing the surface porous structure layer of the graphite felt.
