摘要： First, the present invention involves adding a curing catalyst to a phenolic resin, polyvinyl alcohol, a pore-forming agent, and a cross-linking agent, and mixing, casting, heating, and drying the same. Next, the plate-shaped porous phenolic resin obtained thereby which has uniform consecutive macropores having an average pore diameter in the range of 3 to 35 μm and formed in a three-dimensional network pattern is immersed with an organic solvent. Thereafter, this block is extracted and pressure is applied thereto. It is possible to obtain plate-shaped activated carbon for use in an electrode of a power-storage device by carbonizing and activating a block which has undergone this procedure by keeping the same at an increased temperature.
