▎ 摘  要

NOVELTY - Preparing graphene comprises taking graphite rod as positive and negative electrodes of a work electrode, and taking an electrolyte solution of lithium ions as an electrolyte, with the applied voltage. The charge and discharge operation can be carried out. The graphite electrode is stripped to a thin graphite slice containing lithium ion, and dispersed in the electrolyte. The electrolyte is performed with an ultrasonic treatment, filtered and washed to obtain a graphene solution or a graphene solid. USE - Method for preparing graphene (claimed) used in power supply materials, composite materials, sensors and transistors. ADVANTAGE - The method has low cost, high efficiency and large output.
