| titleOfInvention | Preparation method of sodium-ion battery positive electrode material with multiphase composite layered structure |
| abstract | The invention provides a sodium ion battery anode and a preparation method thereof, wherein the chemical component of the material is Na x Li y Mn a Co b Ni c O 2 Comprising a P-type transition metal phase and Li 2 MnO 3 The material has characteristic diffraction strong peaks at the positions of 15.8 degrees, 15.9 degrees, 37.8 degrees, 39.7 degrees, 45.5 degrees and 49.2 degrees on an XRD pattern. The preparation method of the material comprises the steps of firstly adding salts of various metals and a combustion improver into water, then burning the mixture in a reactor to obtain a precursor, finally carrying out heat treatment on the precursor, and cooling the precursor to room temperature along with a furnace. The material of the invention is Na-P phase and Li 2 MnO 3 A composite structure grown with each other to form Li 2 MnO 3 The layered material with the composite structure of the/Na-P phase coexists can effectively improve the cycling stability and the rate capability of the Na-P phase. The preparation method provided by the invention is simple, the conditions are easy to control, and the industrialization is convenient. |
