▎ 摘　　要

NOVELTY - The preparation of graphene aerogel anode material involves adding graphene oxide to solvent to obtain graphene oxide solution having mass percentage of 0.01-2%, freeze-drying of graphene oxide solution or carrying out hydrothermal treatment to obtain graphene oxide aerogel, reducing graphene aerogel by using hydrazine hydrate or carrying out high temperature heat treatment to obtain ultrahigh conductive polystyrene aerogel, compacting graphene aerogel, or coating on current collector and drying. USE - Preparation of graphene aerogel anode material used for aluminum ion battery (claimed). ADVANTAGE - The method enables preparation of graphene aerogel anode material with high power density and high safety at low cost by simple process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for aluminum ion battery.
