CARBONACEOUS MATERIAL FOR NEGATIVE ELECTRODE ACTIVE MATERIAL FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERIES, NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY NEGATIVE ELECTRODE, NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY, AND PRODUCTION METHOD OF CARBONACEOUS MATERIAL

The present invention provides a carbonaceous material suitable for a negative electrode active material for non-aqueous electrolyte secondary batteries (e.g., lithium ion secondary batteries, sodium ion secondary batteries, lithium sulfur batteries, lithium air batteries) having high charge/discharge capacities, and preferably high charge/discharge efficiency and low resistance, a negative electrode comprising the carbonaceous material, a non-aqueous electrolyte secondary battery comprising the negative electrode, and a production method of the carbonaceous material. The present invention relates to a carbonaceous material having a nitrogen content obtained by elemental analysis of 3.5 mass % or more, a ratio of nitrogen content and hydrogen content (R) of 6 or more and 100 or less, a ratio of oxygen content and nitrogen content (R) of 0.1 or more and 1.0 or less, and a carbon interplanar spacing (d) observed by X-ray diffraction measurement of 3.70 Å or more.
