Artificial graphite particles, a method of manufacturing the same, a non-aqueous electrolyte secondary battery negative electrode, a method of manufacturing the same, and a lithium secondary battery

A plurality of primary particles made of graphite having a set or combined with secondary particle structure, artificial graphite particles edge portion of the primary particles and having a curved layer structure folded into a polygonal shape. The graphite particles are located with a gap, it can be easily produced by the method one or both of passing the two members rotating, the raw material graphite particles into the gap. Further, the lithium secondary battery using the graphite particle as a negative electrode material has excellent high capacity and and rapid charge and discharge characteristics, less cycle deterioration.
