▎ 摘　　要

NOVELTY - Graphite oxide is ultrasonically dispersed in a mixed solvent of water and ethanol, to obtain a graphene oxide suspension. Lithium titanate is ultrasonically dispersed in the graphene oxide suspension, reacted at 50-200 Pa and 180-250 degrees C for 3-10 hours, and filtered to obtain a lithium titanate-graphene composite. USE - Preparation of lithium titanate-graphene composite for use in preparation of lithium ion batteries (claimed). ADVANTAGE - The method provides lithium titanate-graphene composite having excellent adhesion between lithium titanate and graphite, and uniform dispersion of lithium in graphene conductive network. The obtained composite enables preparation of lithium ion batteries having excellent cycle performance and power performance characteristics. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of lithium ion battery.
