    Abstract: A carbon material may include granulated particles satisfying (1L) and (2L): (1L) the granulated particles are made of a carbonaceous material; and (2L) the granulated particles satisfy the relationship |X1?X|/X1?0.2, wherein X is a volume-based average particle diameter determined by laser diffraction, and X1 is an equivalent circular diameter as determined from a cross-sectional SEM image, provided that the cross-sectional SEM image is a reflected electron image acquired at an acceleration voltage of 10 kV, wherein the carbon material has an average box-counting dimension relative to void regions of 30 particles of 1.55 or greater, as calculated from images obtained by randomly selecting 30 granulated particles from a cross-sectional SEM image of the carbon material, dividing the cross-sectional SEM image of each granulated particle into void regions and non-void regions, and binarizing the image. Such carbon material may be used in electrodes and batteries.
