As a core component in new energy vehicles and energy storage, lithium-ion batteries' performance and cost directly determine the competitiveness of the industry. The particle size control, morphology uniformity, and purity of lithium battery raw materials (such as cathode materials, anode materials, and conductive agents) are key factors affecting the battery's energy density, cycle life, and safety. Vertical grinding mills (cell mills), with their efficient ultra-fine grinding, intelligent control, and low pollution characteristics, are widely used in the processing of lithium battery materials, driving the industry towards high-end, intelligent, and green upgrades.

Cathode materials (such as ternary precursors and lithium iron phosphate) require nanometer-level particle size D50: 1-10μm), to increase the contact area between the active material and the electrolyte; Morphology uniformity: particle shape (spherical, flake) and particle size distribution (narrow distribution) affect the material's flowability and compaction density; Purity and pollution control: the content of metal impurities (Fe, Cu, etc.) needs to be below the ppm level to avoid battery self-discharge or short circuits; Production capacity and energy consumption balance: large-scale production requires high throughput while reducing unit energy consumption to achieve low-carbon manufacturing.

Technical Advantages of Vertical Grinding Mills (Cell Mills) ：

Ultra-fine grinding, precise particle size control ， Adopts a vertical structure and multiple level turbines and rotor shearing, combined with intelligent variable frequency control, to achieve high-energy shearing of materials and centrifugal classification, particle size can be down to nanometer level; Low pollution, ensuring material purity ： Wear-resistant material ， The lining uses high-molecular ceramic (such as zirconia) or tungsten carbide to reduce metal contamination; Closed system: fully enclosed grinding chamber ， to prevent material oxidation. High efficiency and energy saving, reducing production costs ： Equipment throughput is high, and can be customized according to customer needs Compared with traditional equipment, the efficiency is improved 30% Energy consumption optimization: the vertical structure reduces mechanical loss, and energy consumption is reduced by 20%-40% ； Modular design: supports seamless switching of multiple process segments, adapting to the customized needs of different materials (such as ternary, lithium iron phosphate, silicon carbon anode).
