Lithium compounds in lithium batteries have specific requirements for particle size distribution, necessitating nano-scale battery materials to significantly improve overall battery performance. As a representative grinding medium for a new generation of nano-battery materials, zirconia grinding beads possess advantages such as high density, high strength, excellent wear resistance, and long service life, enabling nano-scale ultra-fine grinding and dispersion of new energy battery materials.
Zirconia beads collide with and shear battery material particles under the drive of a sand mill, thereby reducing particle fineness. There is a precise 1000-fold ratio relationship between the target fineness of the battery material and the required zirconia bead diameter.
Mainly used for LFP (Lithium Iron Phosphate) material processing.
Mainly used for silicon-carbon composite materials in anodes.
To meet the stringent requirements of high fracture resistance and low wear rate during ultra-fine grinding, manufacturing process quality is vital to achieving a dense internal structure.
Operates on a principle similar to "snowballing". If not properly controlled, it may result in an incompact internal structure with internal pores, negative affecting overall crushing strength, Vickers hardness, and wear resistance.
Involves dropping slurry into a solution for precise one-step molding. Produces a highly uniform, dense internal structure ensuring higher crushing strength, superior Vickers hardness, optimal wear resistance, and automated quality control.
