▎ 摘　　要

NOVELTY - Electrochemically preparing low-structure defect graphene, comprises mixing aqueous electrolyte solution with liquid alkane, inserting an anode and a cathode into the mixed solution and energizing, so that the mixed solution undergoes an energization reaction to obtain graphene slurry, and finally the graphene powder is obtained by washing and drying. USE - The method is useful for electrochemically preparing low-structure defect grapheme. ADVANTAGE - The method has simple production device, no pollution and high yield. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for device for electrochemically preparing low-structure defect graphene
