摘要
Provided by the present invention is a cathode material for a sodium-ion battery with a coating structure and a preparation method therefor. In the present invention, an Na3V2(PO4)3/C cathode material is prepared by means of a sol-gel method. Synthesized zwitterionic polymers may be used as chelating agents and as a carbon source; the process is simple, can quickly form a gel, and the reaction time is shortened contains a zwitterionic structure which may be well dissolved with the precursor of sodium vanadium phosphate to form a stable carbon coating layer. Compared to the prior art, the cathode material for a sodium-ion battery of the present invention enhances the electrical conductivity and cycle performance of the cathode material by means of the doping of nitrogen and sulfur on carbon. At the same time, the prepared cathode material for a sodium-ion battery has sodium vacancies and maintains a stable structure during the process of sodium-ion intercalation/deintercalation.
