▎ 摘  要

NOVELTY - The composite has particles of an electroactive material. A coating layer comprises a set of graphene nanoplatelets (120) comprising a thickness of 0.34 nanometer to 50 nanometer and a lateral dimension of less than 900 nanometer. The electroactive particles comprise a lateral dimension that is larger than the lateral dimension of the graphene nanoplatelets. The graphene nanoplatelets coat a portion of the nanoscale particles to form a layer made up of overlapping graphene nanoplatelets. The graphene nanoplatelets-coated nanoscale particles form agglomerates. USE - Nanographitic composite for use as an anode in a lithium ion battery (claimed) for commercial application. ADVANTAGE - The electroactive particles are allowed into an exfoliation apparatus such that the particle size of the electroactive particle precursor is reduced and electro active material with smaller nanographic platelets is improved, thus improving performance and minimizing the cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for making a nanocomposite suitable for use in a lithium ion battery. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a nanographitic composite. Nanocomposite (100) Silicon particle (110) Graphene nanoplatelets (120)
