    摘要: The present invention relates to a nano-graphite plate structure with N graphene layers stacked together, where N is 30 to 300. The nanometer nano-graphite structure has a tap density of 0.1 g/cm3 to 0.01 cm3, a thickness of 10 nm to 100 nm, and a lateral dimension of 1 μm to 100 μm. The ratio of the lateral dimension to the thickness is between 10 and 10,000. The oxygen content is less than 3 wt %, and the carbon content is larger than 95 wt %. The nano-graphite plate structure has both the excellent features of the graphene and the original advantages of easy processability of the natural graphite so as to be broadly used in various application fields.
