Abstract
The invention includes a method to provide composite graphite particles for a nonaqueous secondary battery negative electrode, wherein metal particles capable of alloying with Li can be internally present with favorable dispersibility. The present invention relates to composite graphite particles for a nonaqueous secondary battery negative electrode containing graphite (A) and metal particles (B) capable of alloying with Li, wherein the degree of dispersion of the metal particles (B) in the composite graphite particles is 0.78 or more.
