Abstract
An apparatus and method to exfoliate a graphite grain is described. A mixture of a graphite grain and an ice grain are transferred into a vessel. The vessel includes an agitator. The agitator agitates the mixture to induce a contact between the graphite grain and the ice grain. The contact between the graphite grain and the ice grain exfoliates the graphite grain.
Claims16
A method to exfoliate a graphite grain, the method comprising:
- transferring a mixture into a vessel,
- wherein the mixture comprises a graphite grain and deionized water,
- chilling the deionized water to partially solidify the deionized water to a crystalline structure which adheres to an outer layer of the graphite grain;
- and
- agitating the mixture to induce a contact between the graphite grain and the crystalline structure to exfoliate the outer layer from the graphite grain, wherein the mixture is agitated in a fluid medium, and wherein the fluid medium comprises a first fluid comprising a liquid, wherein the fluid medium comprises a second fluid, and
- wherein the second fluid comprises at least one of ethylene glycol, n-methyl-2-pyrrolidone, isopropyl alcohol, methyl alcohol, butyl alcohol, or ethyl alcohol.
