▎ 摘  要

NOVELTY - The method involves placing graphene oxide or graphene oxide composite material in a vacuum quartz tube. The prepared micro sheet is tested using laser fast scan heating reduction of sample. A graphene oxide composite paper is adhered on bracket. The graphene oxide composite paper is made of metal or semiconductor doped graphene, graphene oxide-ceramic composite material or graphite-polymer composite. The pure hydrogen is inputted into quartz tube. USE - Large sized graphene micro sheet preparation method for use in lithium ion power battery application. ADVANTAGE - The conductivity and uniformity of the graphene micro sheet can be improved. The structure of the preparation device is simplified and preparation device is provided with flexible operation. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view illustrating large sized graphene micro sheet preparation process. (Drawing includes non-English language text)
