Beschreibung
Zusammenfassung:A graphite material is provided wherein D50% is 2 to 9 μm in particle diameter distribution based on volume as measured by laser diffraction, a specific surface area is 2 to 6 m2/g and no coating layer is substantially included in a surface of the particle. Also provided is a graphite material comprising substantially single-composition particles having an isotropic crystal structure, wherein D50% is 2 to 9 μm in particle diameter distribution based on volume as measured by laser diffraction, and a specific surface area is 2 to 6 m2/g.
