The Hummers’ method is used to prepare graphene oxide and graphene powder, and the obtained powder material contains a large amount of oxygen-containing groups. Due to the effect of strong oxidants, there are many defects on the graphene body. Although a large number of oxygen-containing groups are reduced by the reduction reaction, the defects of the graphene body are numerous, which has a great influence on the conductivity of graphene and also limits the high carrier transport capability and application of graphene itself. Using industrial means, the graphene powder is highly reduced, and the ultrathin graphene powder is obtained, the graphene powder has extremely low impurity content, and the defects are substantially completely reduced. Then, these lay the foundation for its application in the battery industry.

石墨烯氧化还原的结构缺陷及其高效结构重整技术

采用Hummers法制备氧化石墨烯和石墨烯粉体,所得粉体材料中含有大量的含氧基团。由于强氧化剂的作用,石墨烯体上存在许多缺陷。虽然通过还原反应还原了大量的含氧基团,但石墨烯本体的缺陷众多,这对石墨烯的导电性影响很大,也限制了石墨烯本身的高载流子传输能力和应用。采用工业化手段,高度还原石墨烯粉体,得到超薄石墨烯粉体,石墨烯粉体杂质含量极低,缺陷基本完全减少。然后,这些为其在电池行业的应用奠定了基础。
