▎ 摘  要

NOVELTY - Ferrite-ordered intercalated graphene nano-composite and its preparation, involves(1)ultrasonically dispersing graphite oxide in ethylene glycol to prepare uniform dispersion liquid of the graphite oxide, (2)stirring, fully dissolving piperazine in deionized water to prepare piperazine water solution, (3) slowly dripping dispersion liquid into dispersion liquid under stirring condition, and continuously stirring until two are fully and uniformly mixed, (4)transferring mixed solution into three-neck flask, and carrying out condensation reflux, (5) dissolving soluble ferric salt and soluble nickel salt in ethylene glycol, slowly adding mixture into reaction solution under condition of stirring, continuously stirring, uniformly mixing, and then carrying out hydrothermal reaction; and(6) cooling, separating, washing and freeze-drying the reaction liquid to obtain ferrite-ordered intercalated graphene nano-composite. USE - Ferrite-ordered intercalated graphene nano-composite used as negative electrode for lithium-ion battery(claimed). ADVANTAGE - The ferrite-ordered intercalation graphene nano-composite, contact area between electrode and electrolyte can be effectively increased, and lithium storage performance of the electrode material under high current density is improved,improving cycle performance, rate capability and high-temperature stability of the lithium ion battery cathode material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for ferrite-ordered intercalated graphene nanocomposite material prepared by the preparation method.
