▎ 摘  要

NOVELTY - Preparing graphene based on lithium peroxide embedded in graphite layer comprises discharging the lithium-oxygen battery composed of metallic lithium or other lithium-rich materials as the cathode and graphite carbon as the anode, embedding the generated lithium peroxide in the graphite carbon electrode, and removing the lithium peroxide embedded in the graphite-based carbon electrode. USE - The method is useful for preparing graphene based on lithium peroxide embedded in graphite layer. ADVANTAGE - The method: overcomes slower preparation speed and higher cost of the graphene preparation method; has poor quality defects, high-quality graphene under mild conditions and at a lower cost, less energy loss; at the same time, has no pollution during the production process; and collects and recycles by-products obtained by the reaction, thus reduces production costs.
