▎ 摘　　要

NOVELTY - Preparing 2-aminofluorene-modified graphene oxide lithium ion battery anode material comprises (i) adding graphene oxide sheet to dimethylformamide (DMF) solution and uniformly and ultrasonically dispersing to obtain graphene oxide solution, then adding carbodiimide and N-hydroxysuccinimide into the DMF solution, uniformly and ultrasonically dispersing, then drop wisely adding into the graphene oxide solution used to activate carboxy group on graphene oxide; (ii) ultrasonically dispersing 2-aminopurine in DMF solution to obtain AAQ solution, drop wisely adding AAQ solution into the dispersion obtained in the step (i); and (iii) subjecting the dispersion obtained in the step (ii) to a nitrogen gas reaction, centrifuging with ethanol, washing, and freeze-drying. USE - The method is useful for preparing 2-aminofluorene-modified graphene oxide lithium ion battery anode material. ADVANTAGE - The anode material has high electrical conductivity, high specific surface area, high specific capacity and good cycle stability. The method is simple and economical.
