Carbon material composition, method for producing carbon material composition, negative electrode, and secondary battery

The present invention pertains to a carbon material composition containing: a carbon material (A) that contains graphite having an amorphous carbonaceous substance or a graphitic substance and that has a pore distribution having two or more peaks as measured by mercury intrusion method; y < =-0.0084 x + 0.13 is satisfied, where y (mL/g) is the cumulative pore volume equal to or less than the minimum value between the peak having the smallest pore diameter and the next peak, and x (%) is the coating rate of an amorphous carbonaceous substance or a graphitic substance of graphite; the carbon material (B) has a pellet density of 1.80 g/cm3 or more. 本发明涉及一种碳材料组合物，其包含碳材料(A)和碳材料(B)，所述碳材料(A)包含具有非晶态碳质物或石墨质物的石墨，通过水银压入法测定的细孔分布具有2个以上的峰，将细孔直径最小的峰与下一个峰之间的极小值以下的累积细孔容积设为y(mL/g)、将石墨的非晶态碳质物或石墨质物的包覆率设为x(％)时，满足y≤-0.0084x+0.13；所述碳材料(B)的粒料密度为1.80g/cm3以上。
