| titleOfInvention | Crystal material, preparation method and use thereof, positive electrode material for sodium ion battery, sodium ion battery, and apparatus |
| abstract | The present application discloses a crystal material, a preparation method and a use thereof, a positive electrode material for a sodium ion battery, a sodium ion battery, and an apparatus, relating to the technical field of sodium ion batteries. The crystal material is represented by a chemical formula of Na2M(C2O4)X·nH2O, where M is at least one positive divalent metal, X is a negative divalent anionic group, and X is not (C2O4), 0≤n≤12. The crystal material belongs to a hexagonal crystal system and has a three-dimensional skeleton structure. Sodium ions and water molecules do not participate in the construction of the skeleton. The crystal material has an excellent charge-discharge specific capacity and a high redox potential, and can significantly improve the structural stability of a positive electrode active material. This application resolves the defects of a complex preparation process, high costs, and unsatisfactory stability of existing positive electrode material for sodium ion batteries. The positive electrode material for a sodium ion battery provided by the present application has the advantages of high sodium insertion performance, high redox potential, excellent cycle stability, and low costs. |
