Abstract

See full text

A non-flaky carbon material having specific optical structures, wherein the ratio between the peak intensity I110 of (110) plane and the peak intensity I004 of (004) plane of a graphite crystal determined by the powder XRD measurement, I110/I004, is 0.10 or more and 0.35 or less; an average circularity is 0.80 or more and 0.95 or less; d002 is 0.337 nm or less; and the total pore volume of pores having a diameter of 0.4 μm or less measured by the nitrogen gas adsorption method is 25.0 μl/g or more and 40.0 μl/g or less. Also disclosed is a method for producing the carbon material, a carbon material for a battery electrode, a paste for an electrode incorporating the carbon material for a battery electrode, an electrode for a lithium battery incorporating a formed body of the paste for an electrode, a lithium-ion secondary battery including the electrode and a method for producing the electrode.
