Artificial graphite material, method for producing artificial graphite material, negative electrode for lithium ion secondary battery, and lithium ion secondary battery |
| abstract |
PROBLEM TO BE SOLVED: To provide an artificial graphite material which can be used as a material for a negative electrode for a lithium ion secondary battery to obtain a lithium ion secondary battery whose discharge capacity does not easily deteriorate even when charging and discharging are repeated at a low temperature of 0 ° C. or lower. .. A crystallite size L (112) in the c-axis direction calculated from a (112) diffraction line obtained by an X-ray wide-angle diffraction method is 4 to 30 nm, and is measured by a laser diffraction type particle size distribution measuring device. With an artificial graphite material having a calculated volume reference surface area of 0.22 to 1.70 m2 / cm3, an oil absorption of 67 to 147 mL / 100 g, and a nitrogen adsorption specific surface area of 3.1 to 8.2 m2 / g. do. [Selection diagram] None |
