▎ 摘  要

NOVELTY - Producing graphene, comprises (i) preparing porous carbide-derived carbon by subjecting crystalline carbide compound and halogen element-containing gas to thermochemical reaction; (ii) subjecting carbide-derived carbon to acid treatment, to obtain oxide of carbide-derived carbon; and (iii) subjecting oxide of carbide-derived carbon to reduction reaction. USE - The graphene is useful in secondary cell electrode, namely lithium ion secondary battery electrode, supercapacitor electrode or fluorine-based capacitor electrodes, and secondary battery cathode, lithium battery cathode material, and carbon cathode material. ADVANTAGE - The method improves the mobility of the ions in the product.
