Graphite material, carbon material for battery electrode, and battery
A graphite material having pores which, when 200 rectangular regions of 6 μm×8 μm are randomly selected in a surface image of the graphite material observed by a scanning electron microscope, in the surface of the graphite material appearing in the regions, a pore appearing on the surface and having an aperture in a shape having a diameter of 15 nm to 200 nm, a circularity degree of 0.75 to 1.0 and a major axis/minor axis ratio of 1.0 to 1.5 is visible in two regions or more. Also disclosed is a carbon material for battery electrodes, a paste for electrodes, an electrode and a lithium ion secondary battery including the graphite material.
