| titleOfInvention | A kind of spray drying preparation method of lithium transition metal salt cathode material and its use in lithium ion battery |
| abstract | The invention discloses a method for preparing a lithium transition metal salt positive electrode material, which comprises the following steps: (1) preparing a transition metal salt into an aqueous solution; (2) spraying and granulating the above solution through a spray drying device to obtain a transition metal acid salt precursor; (3) pre-calcining the precursor obtained in step (2) in an oxygen atmosphere to obtain a transition metal oxide; (4) mixing the transition metal oxide obtained in step (3) with a lithium source and calcining to obtain Lithium transition metalate cathode material (NCM/NCA): its crystals have α‑NaFeO 2 (space group R ) layered structure, I 003 /I 104 in the XRD pattern is greater than 1.2, and the unit cell parameter c/a is greater than 4.9. The surface area is 1 to 10 m 2 /g. The preparation method of the lithium transition metal salt cathode material involved in the invention has the advantages of simple process, high production efficiency, uniform and controllable particle size of the material, good crystal structure, and has high specific capacity and good rate performance when applied to a lithium ion battery. |
