Raw material composite for carbon material used in electric double layer capacitor, manufacturing method of the same, electric double layer capacitor, and manufacturing method of the same
A raw material composite 10 for a carbon material used in an electric double layer capacitor contains microcrystalline carbon having a layered crystal structure similar to graphite, and is formed a carbon material for an electric double layer capacitor by undergoing an activation treatment. Here, the raw material composite is characterized in that a Hardgrove grindability index HGI defined by ASTMD-409-71 is 50 or above, an interlayer distance d002 of the microcrystalline carbon determined by an X-ray diffraction method is 0.343 NM or below, and a crystallite size Lc002 of the microcrystalline carbon determined by the X-ray diffraction method is 3.0 nm or below.
