▎ 摘　　要

NOVELTY - Method for preparing surface fluorinated lithium titanate/graphene composite nanomaterial, involves (a) uniformly dispersing graphene oxide in a solvent to obtain a graphene oxide solution, (b) uniformly dispersing a titanium source in an aqueous hydrogen peroxide solution containing a lithium source, adding the graphene oxide solution, uniformly mixing and reacting at 160-200 degrees C for 3 hours to obtain a lithium titanate/graphene oxide composite, (c) adding the lithium titanate/graphene oxide composite to an ammonium bifluoride solution and reacting at 160-200 degrees C for more than 3 hours to prepare a surface fluorinated lithium titanate/graphene oxide composite, and (d) carrying out high-temperature sintering on the surface fluorinated lithium titanate/graphene oxide composite under the protection of inert atmosphere containing hydrogen to obtain the finished product. USE - The method is useful for preparing surface fluorinated lithium titanate/graphene composite nanomaterial (claimed). ADVANTAGE - The composite nanomaterial is prepared by simple method and has excellent performance and excellent stability without using high-concentration acid and alkali as raw material.
