The invention relates to a method of massively preparing graphene nano sheet powder by using graphite powder as a precursor. The method comprises the following steps: mixing graphite powder and sodium sulfate according to a mass ratio of 1:200 to 1000, subjecting the mixture to a ball-milling process with a high-speed ball mill for 8 to 12 hours, then washing the powder with distilled water to remove sodium sulfate, filtering, and then drying the product at a temperature of 80 to 120 DEG C so… CONTINUE READING
