<P>PROBLEM TO BE SOLVED: To provide a method for producing a carbonaceous electrode material free from warpage and delamination defects. <P>SOLUTION: Two or more carbon staple fiber paper sheets produced by making paper sheets by a paper-making step, continuously pressing the sheets between papermaking felts and drying by contacting with a hot roll are impregnated with a phenolic resin, and the phenolic resin is carbonized to obtain the carbonaceous electrode material composed of two or more carbon staple fiber sheets laminated through carbonized phenolic resin. The carbon staple fiber is obtained by the papermaking treatment of a dispersion produced by dispersing carbon staple fibers, binder fibers, and polyethylene pulp or vinylon fibers in water. <P>COPYRIGHT: (C)2010,JPO&INPIT |
