▎ 摘  要

NOVELTY - A cathode material comprises graphene oxide.cerium dioxide (CeO2)/carbon nanosheet. USE - Cathode material for use in a sodium ion battery of an electric vehicle industry and renewable energy e.g. wind energy and solar energy. ADVANTAGE - The method enables to prepare sodium ion battery cathode material that has high stability and specific capacity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) preparation method of the cathode material of sodium ion battery, comprising mixing the carbon nanosheet and solvent, adding adhesive and CeO2, stirring, conducting water bath reaction and solid-liquid separation, taking the solid phase to obtain carbon nanosheet/CeO2 composite material, adding the carbon nanosheet/CeO2 composite material into graphene oxide solution, stirring, conducting solid-liquid separation, taking solid phase and calcining.; and (2) a battery.
