CARBON MATERIAL FOR ELECTRODE

PROBLEM TO BE SOLVED: To provide a carbon material that has a high electrode filling property of material, high energy density, and a quick charge/discharge property, by setting average grain size to be a specific value, surface interval of specific surfaces in a large angle X-ray diffraction method to be shorter than a specific value, specific surface area in a BET method to be less than a specific value, and tap density to have a specific relation with average grain size of the carbon material. SOLUTION: Average grain size is 2-35 μm, surface interval (d002) of a (002) surface in a large angle X-ray diffraction method is shorter than 0.337 nm, specific surface area in a BET method is less than 18 m2/g, and tap density is in a range of a formula (TD: tap density of carbon material (g/cm3), and AP: average grain size of the carbon material (μm)). In argon ion laser Raman spectrum, preferably, ratio of peak strength at 1580 cm-1 to peak strength at 1360 cm-1 is not higher than 0.9, half band width of the peak at 1580 cm-1 is not higher than 26 cm-1. After the carbon material for an electrode is mixed with organic compound, the organic compound is carbonized for manufacture.
