    摘要： An amorphous carbon material for lithium-ion secondary battery negative electrode is capable of reducing capacity degradation due to repeated charge and discharge cycles, storage while being charged, or floating charge.
    A method for producing an amorphous carbon material for a negative electrode of a lithium-ion secondary battery includes the steps of: pulverizing and classifying a raw coke composition obtained from a heavy-oil composition undergone coking by delayed coking process to obtain powder of the raw coke composition, the raw coke composition having a H/C atomic ratio that is a ratio of hydrogen atoms H and carbon atoms C of 0.30 to 0.50 and having a micro-strength of 7 to 17 mass%; giving compressive stress and shear stress to the powder of the raw coke composition to obtain a carbonized composition precursor; and heating the carbonized composition precursor under an inert atmosphere at a temperature from 900°C to 1,500°C so that a size of a crystallite Lc(002) is in a range of 2 nm to 8 nm, the size being calculated from a (002) diffraction line obtained by X-ray wide-angle diffractometry.

    摘要： Provided is a carbon material for negative electrode capable of suppressing capacity degradation due to repeated charge and discharge cycles, storage while being charged or floating charge.
    A graphite material having lattice distortion for lithium-ion secondary battery negative electrode is obtained by a manufacturing method comprising the steps of: pulverizing and classifying a raw coke composition obtained from a heavy-oil composition undergone coking by delayed coking process, the raw coke composition having a H/C atomic ratio that is a ratio of hydrogen atoms H and carbon atoms C of 0.30 to 0.50 and having a micro-strength of 7 to 17 mass% to obtain powder of the raw coke composition; giving compressive stress and shear stress to the powder of the raw coke composition so that average circularity is 0.91 to 0.97 to obtain round powder; heating the round powder to obtain a carbonized composition; and graphitizing the carbonized composition. The graphite material has a size of a crystallite Lc(112) of 4 nm to 30 nm, the size being calculated from a (112) diffraction line obtained by X-ray wide-angle diffractometry, and has lattice distortion in the range from 0.001 to 0.085, the lattice distortion being calculated from a (004) diffraction line and a (006) diffraction line.
