▎ 摘　　要

NOVELTY - Graphite composition material covered by a fast ion conductor comprises inner core and an outer shell covering the inner core. The inner core is graphite. The outer shell is of a double-layer structure, and the inner layer is a first coating layer and contains a fast ion conductor and the outer layer is a second coating layer and is nitrogen-containing amorphous carbon. USE - The composite material is useful for graphite composite covered by a fast ion conductor. ADVANTAGE - The material has high conductivity, and improves the bonding force, and improves cycling performance and power performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing of graphite composition material, comprising (i) uniformly dispersing the fast ion conductor and graphene oxide N-methylpyrrolidone conductive liquid into an organic solvent, reacting at 100-200℃ and 1-5 Mpa for 1-6 hours, filtering and vacuum drying to obtain coating material A, (ii) implanting the coating material A on the artificial graphite surface by the particle injection method to obtain material B, and (iii) adding conductive polymer and 1-10 wt.% hydrochloric acid solution into the coupling agent solution, mixing uniformly, adding the material B, uniformly dispersing, adding an organic flux to dilute, spray drying, pulverizing, carbonizing, pulverizing, and classifying.
