As a representative of the latest generation of nano battery materials, zirconia grinding beads have advantages such as high density, high strength, good wear resistance, and long service life, which can achieve nano level ultrafine grinding and dispersion of new energy battery materials.

Lithium compounds in lithium batteries have specific requirements for particle size distribution, so it is necessary to use nanoscale battery materials to improve battery performance. As a representative of the latest generation of nano battery materials, zirconia grinding beads have advantages such as high density, high strength, good wear resistance, and long service life, which can achieve nano level ultrafine grinding and dispersion of new energy battery materials.

The grinding principle of zirconia grinding balls is that the zirconia grinding balls collide and shear the battery material particles under the driving force of the sand mill, thereby achieving the effect of reducing particle fineness. They have distinct characteristics in the grinding application of positive and negative electrode materials.

The application of zirconia grinding balls in positive electrode materials is mainly made of lithium iron phosphate material, while the negative electrode is mainly made of silicon carbon negative electrode. The target fineness of the two is greatly different: the former is worth noting that both lithium iron phosphate and silicon carbon negative electrode materials have a common feature of using a rod pin sander for grinding.

The rod pin sand mill has a high linear speed and a large amount of kinetic energy transmitted to grind zirconia grinding media balls, making it suitable for efficient grinding of battery materials; At the same time, higher requirements have been put forward for the performance of zirconia grinding balls used in it, requiring good wear resistance and less prone to breakage.
