▎ 摘　　要

NOVELTY - Preparation of multi-atomic doped three-dimensional graphene involves carrying out hydrothermal reaction of a dispersion containing melamine and graphene oxide to obtain a preform, adding heteroatomic source with doping atoms, crushing, uniformly polishing, and calcining under protection of atmosphere. USE - Preparation of multi-atomic doped three-dimensional graphene used as anode material in lithium ion batteries and sodium ion batteries. ADVANTAGE - The method enables simple and economical preparation of multi-atomic doped three-dimensional graphene with controllable doping state. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for multi-atomic doped three-dimensional graphene prepared by the method.
