Abstract
A carbon material may include granulated particles made of a carbonaceous material and satisfying (2L), wherein X is a volume-based average particle diameter determined by laser diffraction, and Xis an equivalent circular diameter determined from a cross-sectional SEM image, which is a reflected electron image acquired at 10 kV, wherein the carbon material has an average inter-void distance Z of 30 granulated particles randomly selected from a cross-sectional SEM image of the carbon material, as Zave, and wherein the carbon material has volume-based average particle diameter X determined by laser diffraction in a Zave/X ratio of 0.060 or less.
