▎ 摘　　要

NOVELTY - An anode active material comprises reduced graphene oxide comprising 2-2.75 atomic% nitrogen, and an amine group substituted on a surface of the reduced graphene oxide. USE - Active material is used for forming anode for lithium-air battery (claimed). ADVANTAGE - The anode active material provides lithium-air battery having improved electrochemical property with suppressed decrease in specific surface area and porosity of reduced graphene oxide due to pi - pi restacking agglomeration.
