▎ 摘　　要

NOVELTY - Use of fluorinated graphene in a secondary sodium battery, is claimed, where the fluorinated graphene is a fluorinated graphene having a fluorocarbon-containing semi-ionic bonds, and formed by thermal intercalation of chlorine atoms and fluorine atoms formed between the halogen bond resulting in conversion of a part of the carbon-fluorine covalent bond into carbon-fluorine semi-ionic bond, and the fluorinated graphene containing fluorocarbon-containing semi-ionic bonds is used as a positive electrode material for secondary sodium batteries. USE - Fluorinated graphene for use as positive electrode material in secondary sodium battery. ADVANTAGE - The fluorinated graphene improves charging and discharging platform, high reversible specific capacity and stable discharge platform of sodium secondary battery positive electrode material.
