METHOD FOR MANUFACTURING POROUS ELECTRODE BASE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method capable of improving a carbonization yield without depending on a resin component to be mixed in paper making even having a carbonization process, the method capable of a porous carbon electrode base material with high electrical conductivity.SOLUTION: The method of manufacturing a porous carbonaceous electrode base material comprises: the step (1) of manufacturing a paper body in which short carbon fibers (A), short carbon fiber precursor fibers (b) and/or fibril-like fibers(b') are dispersed; the step (2) of heat-treating the paper body for 10-300 seconds at 300-450°C under an oxygen environment to obtain a precursor sheet of a porous electrode base material; and the step (3) of carbonizing the precursor sheet obtained in the step (2) at 2000-3000°C under a nitrogen atmosphere to manufacture the porous carbonaceous electrode base material.
