NOVELTY - A negative electrode material comprises a carbonaceous material and a graphite material. The carbonaceous material is obtained by carbonizing a plant-derived organic substance. The carbonaceous material contains 0.5 %mass or less potassium, and has average particle diameter of 2-50 mu m, and density of 1.51-1.65 g/cm3. The atomic ratio of hydrogen atoms with respect to carbon atoms contained in the carbonaceous material is 0.1 or less. The average layer surface interval of the graphite material is 0.345 nm or less, when measured using X-ray powder diffractometry.    USE - Negative electrode material is used for negative electrode of non-aqueous electrolyte secondary battery used for vehicle (all claimed) e.g. electric vehicle, hybrid vehicle and motor vehicle, and portable electronic device e.g. mobile telephone and notebook personal computer.    ADVANTAGE - The negative electrode material has reduced moisture-absorbing property, and provides the non-aqueous electrolyte secondary battery e.g. lithium-ion secondary battery with excellent charging and discharging cyclic characteristics.    DETAILED DESCRIPTION - A negative electrode material comprises a carbonaceous material and a graphite material. The carbonaceous material is obtained by carbonizing a plant-derived organic substance. The carbonaceous material contains 0.5 %mass or less potassium, and has average particle diameter of 2-50 mu m, and density of 1.51-1.65 g/cm3, when measured using butanol method. The atomic ratio of hydrogen atoms with respect to carbon atoms contained in the carbonaceous material is 0.1 or less. The average interplanar distance of plane (002) in the carbonaceous-material is 0.365-0.4 nm, when measured using X-ray powder diffractometry. The graphite material has true density of 1.9 g/cm3, when measured using butanol by pycnometer method. The average layer surface interval of the graphite material is 0.345 nm or less, when measured using X-ray powder diffractometry. INDEPENDENT CLAIMS are included for the following:    (1) negative electrode;    (2) non-aqueous electrolyte secondary battery; and    (3) vehicle.
