  • GRAPHENE STRUCTURE, METHOD OF PRODUCING GRAPHENE AND LITHIUM-ION BATTERY ELECTRODE INCLUDING GRAPHENE
    Publication number: 20190221849
    Abstract: A method of producing graphene including the following steps is provided. A graphite material is dispersed in a solution to form a graphite suspension solution. A first crushing process and a second crushing process are performed on the graphite suspension solution sequentially to crush the graphite material, so as to form the graphene. The first crushing process includes applying a first pressure to the graphite suspension solution, and the second crushing process includes applying a second pressure to the graphite suspension solution. The second pressure is greater than the first pressure.
