NOVELTY - Preparation method of fast charging graphite composite material, involves (1)uniformly dispersing rare earth compound,dispersing agent and metal coupling agent into the organic solvent, adding graphite, dispersing uniformly, then adding alkaline solution for co-deposition reaction, filtering, drying, carbonizing to obtain graphite precursor material; (2) taking graphite precursor material as substrate, fast ion conductor/rare earth compound/conductive agent composite as target, by atom vapor deposition, coating target on substrate to obtain fast-charging graphite composite material. USE - Preparation method of fast charging graphite composite material. ADVANTAGE - The doped rare earth metal to expand interlayer distance of graphite, improves de-embedding rate of lithium-ion, co-deposition method can realize uniform metal doping on surface of graphite, and fast charging performance and cycle performance of fast ion conductor lifting material with high lithium-ion conductivity are coated on outer layer by using atomic gas phase deposition method.
