Kaedah pengeluaran prekursor (Ni1/3Co1/3Mn1/3) 3O4 untuk bahan elektrod positif litium mangan nikel kobalt
The production method for the precursor (Ni1/3Co1/3Mn1/3) 3O4 of nickel cobalt manganese lithium positive electrode material involves several key steps.
Pertama sekali, the preparation of nickel cobalt manganese alloy powder is conducted by combining metal nickel, kobalt, dan mangan dalam nisbah molar sebanyak 1:1:1. Under nitrogen protection, the mixture is heated and melted. The molten metal liquid is then atomized using high-pressure nitrogen gas flow, mengakibatkan pembentukan serbuk aloi mangan nikel kobalt. These particles exhibit a regular spherical shape with a loose density of 5.1 g/cm3 dan ketumpatan padat sebanyak 5.6 g/cm3. The high-temperature melting process allows for the uniform mixing of nickel, kobalt, and manganese at the atomic level, promoting the subsequent production of highly homogeneous nickel cobalt manganese oxides.
The next step involves oxidizing the nickel cobalt manganese alloy powder to obtain nickel cobalt manganese oxide. The alloy powder is placed inside an oxidation furnace equipped with stirring and ventilation. By introducing compressed air at a pressure of 0.7 MPa and maintaining dynamic conditions, the material undergoes roasting and oxidation. Proses pengoksidaan dijalankan pada suhu 900 ℃ untuk tempoh 3 Jam. Afterward, the oxidized product is transferred to an airflow mill for crushing treatment. This step requires an air consumption of 1.5 m3/min at an air pressure of 0.8 MPa. Nikel kobalt mangan oksida yang terhasil (Ni1/3Co1/3Mn1/3) 3O4 exhibits an average particle size (D50) daripada 15 μm. It possesses a loose density of 2.1 g/cm3 dan ketumpatan padat sebanyak 2.7 g/cm3. The oxide structure of the nickel cobalt manganese oxide is well-formed, and the particles exhibit a uniform spherical shape.
In summary, the production method for the precursor (Ni1/3Co1/3Mn1/3) 3O4 involves the preparation of nickel cobalt manganese alloy powder through melting and atomization processes. Seterusnya, the alloy powder is oxidized at high temperature, resulting in the formation of nickel cobalt manganese oxide. This method ensures the production of highly homogeneous oxide particles with favorable characteristics for their application as positive electrode materials in nickel cobalt manganese lithium batteries.
