DETAILED DESCRIPTION - Manufacture and extraction of graphene from graphene aggregate involves placing group of scaly graphite particles or group of aggregated graphite particles on parallel plate electrodes, immersing parallel plate electrodes in container filled with methanol, superimposing other parallel plate electrode on one parallel plate electrode, and the scaly graphite particles or the lump graphite particles are interposed, separating two parallel plate electrodes from each other and immersed in methanol, applying direct current potential difference to the gap between the two parallel plate electrodes in which electric field corresponding to magnitude of the potential difference divided by the size of the gap between two parallel plate electrodes is generated, applying electric field to group of scaly graphite particles or group of aggregated graphite particles, destroying interlayer bonds of all the graphite crystals forming the scaly graphite particles or aggregated graphite particles by the application of this electric field, forming graphene in the gap between the two parallel plate electrodes, expanding gap between the two parallel plate electrodes which are incline in methanol, and vibrations in three directions of left and right, front and back, and up and down are repeatedly applied to the container to allow the graphene together from the gap between the two parallel plate electrodes. The container comprises homogenizer apparatus with methanol, and separating graphene through the methanol, applying impact to graphene aggregate via the methanol, with vibrations in three directions of left-right, front-back, and up-down are repeatedly applied to the container to form a collection of graphene in which the flat surfaces of the graphene are overlapped with each other via methanol. The homogenizer device is taken out from the container comprising organic compound with property (a) having a melting point of more than 10 degrees C, and property (b) of being dissolved in methanol and property (c) having viscosity is more than 50 times which is more than methanol. The methanol filled in the container is mixed with the container in an amount that increased the viscosity by 30-40 times. The organic compound is dissolved in the methanol, and vibrations in three directions of front-back, left-right, and up-down are repeatedly applied to the container. A suspension comprises group of graphene in which the flat surfaces of the graphene are overlapped with each other via a methanol solution of the organic compound, and formed on the bottom surface of the container as the shape of the bottom surface, which is supplied to an airflow type crusher, and continuously collided with each other in the crusher. The suspension is separated into individual graphene covered with a methanol solution of the organic compound and taken out from the pneumatic grinder and transferred to a new container, and heating the new container to the boiling point of the methanol to vaporize the methanol, and lowered to a temperature less than the melting point of the organic compound to solidify the organic compound. The graphene covered with the methanol solution of the organic compound be each and every graphene covered by the solid of the organic compound.
