    摘要： The object of the present invention is to provide a carbonaceous material which is obtainable from plant-derived char and has a decreased specific surface area. Further, the object of the present invention is to provide a non-aqueous electrolyte secondary battery having excellent dedoping capacity (discharge capacity), non-dedoping capacity (irreversible capacity), and charge-discharge efficiency.The object can be solved by a carbonaceous material for non-aqueous electrolyte secondary batteries characterized in that the carbonaceous material is obtained by heat-treating plant-derived char which is demineralized in gas-phase, and carbon precursor (i.e. non-graphitizable carbon precursor, graphitizable carbon, or mixture thereof) or volatile organic compound under a non-oxidizing gas atmosphere; and a specific surface area determined by a BET method is 10 m2/g or less. Further, the object can be solved by a carbonaceous material for non-aqueous electrolyte secondary batteries characterized in that the carbonaceous material is obtained by heating plant-derived char, and hydrocarbon compound having 1 to 20 carbon atoms; and a specific surface area determined by a BET method is 15 m2/g or less.
