Carbon material, material for a battery electrode, and battery

A carbon material, the carbon material having a scale-like shape, wherein the ratio IG/ID (R value) between the peak intensity (ID) of a peak in a range of 1300 to 1400 cm−1 and the peak intensity (IG) of a peak in a range of 1580 to 1620 cm−1 measured by Raman spectroscopy spectra when particles of the carbon material are measured with Raman microspectrometer is 0.38 or more and 1.2 or less and the average interplanar spacing d002 of plane (002) by the X-ray diffraction method is 0.335 nm or more and 0.338 nm or less;

• and by observing the optical structures in the cross-section of the formed body made of the carbon material in a rectangular field of 480 μm×640 μm under a polarizing microscope, when areas of the optical structures are accumulated from a smallest structure in an ascending order, SOP represents an area of an optical structure whose accumulated area corresponds to 60% of the total area of all the optical structures;
• when the structures are counted from a structure of a smallest aspect ratio in an ascending order, AROP represents the aspect ratio of the structure which ranks at the position of 60% in the total number of all the structures;
• and when D50 represents a volume-based average particle diameter by laser diffraction method;
• SOP, AROP and D50 satisfy the following relationship:
• 1.5≤AROP≤6 and
• 0.2×D50≤(SOP×AROP)1/2<2×D50.
