  • Method for producing graphite oxide
    Patent number: 11286166
    Abstract: The present invention provides a safe and highly efficient method for producing graphite oxide. The present invention relates to a method for producing graphite oxide by oxidizing graphite, the method including the step of oxidizing graphite by adding a permanganate to a liquid mixture containing graphite and sulfuric acid while maintaining the concentration of heptavalent manganese at 1% by mass or less in 100% by mass of the liquid mixture.
    Type: Grant

  • METHOD OF PRODUCING THIN PLATE-SHAPED GRAPHITE PRODUCT, FLAKY GRAPHITE, AND METHOD OF PRODUCING FLAKY GRAPHITE
    Publication number: 20210309524
    Abstract: A thin plate-shaped graphite product is produced by applying a current to an electrochemical reaction system including a graphite-containing anode, a cathode optionally containing graphite, and an electrolyte solution containing tetrafluoroboric acid or hexafluorophosphoric acid as an electrolyte. Flaky graphite is produced by subjecting the thin plate-shaped graphite product to delamination.
