Power batterie Lithium battery cell slurry stirring is the mixing and dispersion process in the entire production process of lithium-ion batteries, which has a degree of impact on product quality greater than 30%, and is the most important link in the entire production process. car electr batteri or car electr batteri or car electr batteri.
In the manufacture of electrodes for lithium-ion batteries, the positive electrode slurry is composed of binder, conductive agent, and positive electrode material; the negative electrode slurry is composed of binder, graphite carbon powder, etc. The preparation of positive and negative electrode slurry includes a series of technological processes such as the mutual mixing, dissolution and dispersion of liquid and liquid, liquid and solid materials, and this process is accompanied by changes in temperature, viscosity, and environment. In the positive and negative slurry, the dispersibility and uniformity of the granular active material directly affects the movement of lithium ions between the two poles of the battery, so the mixing and dispersion of the slurry of each pole piece material in the production of lithium ion batteries is very important , The dispersion quality of the slurry directly affects the quality of subsequent lithium-ion battery production and the performance of its products.

The ultra-fine dispersion is carried out in the traditional process. This is because: through the traditional mixing and stirring equipment, only the large powder clusters in the solution can be broken up and evenly distributed; however, the powder form is stored in the form of fine powder clusters. In the solution, only the processing requirements of macroscopic dispersion are met. The slurry after macroscopic stirring and dispersion, under the strong mechanical cutting force of the ultrafine dispersion and homogenization equipment, can further break up and homogenize the fine powder or solid particle agglomerates in the solution to obtain a sufficiently fine solid The particles are evenly distributed in the solution to achieve the effect of microscopic ultrafine dispersion and homogenization, which can significantly improve the overall performance of the slurry.
