    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 m 2 /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 m 2 /g or less.

    摘要: The object of the present invention is to provide a manufacturing method of carbonaceous material for a negative electrode of lithium ion capacitors, wherein the carbonaceous material is obtained from plant-derived char as a source, potassium and iron are sufficiently removed, and an average particle diameter thereof is small; and a carbonaceous material for a negative electrode of lithium ion capacitors. The object can be solved by a method for manufacturing a carbonaceous material having an average diameter of 3 to 30µm, for a negative electrode of lithium ion capacitors comprising the steps of: (1) heating plant-derived char having an average particle diameter of 100 to 10000µm at 500°C to 1250°C under an inert gas atmosphere containing a halogen compound to demineralize in a gas-phase, (2) pulverizing a carbon precursor obtained by the demineralization in a gas-phase, (3) calcining the pulverized carbon precursor at less than 1100°C under a non-oxidizing gas atmosphere.
