▎ 摘 要
NOVELTY - Production of three-dimensional porous graphene material comprises ultrasonically dispersing graphene oxide or modified graphene oxide in deionized water, sequentially adding resorcinol and aldehyde while stirring, sonicating, placing into hydrothermal reactor, hydrothermally reacting to obtain crude product, washing, and drying to obtain surface-grafted graphene oxide; and soaking in alkali solution, stirring, filtering, placing into tube furnace, calcining under nitrogen atmosphere, centrifuging, washing with dilute acid solution, and drying. USE - Method for production of three-dimensional porous graphene material used for lithium ion battery (claimed). ADVANTAGE - The material has larger specific surface area, stable structure and high electrochemical performance.
