Abstract
The graphite is a composite between graphite particles and other fine, solid element particles, in which the graphite particles account for at least 40 atomic % and the other element particles have particle sizes of 900 nm or smaller and are dispersed in said graphite particles. The other elements may be Li and Si. Preferably, a part of said other elements forms an intercalation compound with graphite. The composite is suitable for a negative electrode of lithium secondary batteries having large discharging capacity, and as adsorbent materials of adsorbing various substances.
