<p>The purpose of the present invention is to provide composite graphitic particles that can form a dense conductive network in an electrode when forming an electrode of a nonaqueous electrolyte secondary battery such as a lithium ion secondary battery or the like, and to provide a method for manufacturing the same. These composite graphitic particles can include graphite, conductive carbonaceous fine particles, and non-graphitic carbon. The graphite is preferably natural graphite, and more preferably is a spherical graphite granule formed by aggregating a plurality of natural graphite flakes. Furthermore, the graphite is preferably smoothed. The conductive carbonaceous fine particles are directly adhered to the graphite. The non-graphitic carbon is at least partially adhered to the conductive carbonaceous fine particles and the graphite. Furthermore, when a predetermined external force is applied to the composite graphitic particles, the conductive carbonaceous fine particles detach from the graphite.</p> |
