Yttria Stabilized Zirconia Beads for Lithium Battery Slurry Grinding 95% YSZ Media for Nano Milling

As a representative grinding medium for the latest generation of nanobattery materials, zirconia grinding beads offer the advantages of high density, high strength, good wear resistance and long service life. They enable nanoscale ultrafine grinding and dispersion of new energy battery materials.

For cathode materials, zirconia beads are mainly used for LFP (lithium iron phosphate); for anode materials, the main application is siliconcarbon anodes.The target fineness differs greatly between the two:

• LFP: ＜ 350 nm
• Siliconcarbon anode: ＜ 100 nm

Since the final fineness of battery materials directly determines the selection of zirconia bead size, and there is approximately a 1000× ratio, the recommended bead sizes are:

• 35 mmfor LFP materials
• 1 mmfor siliconcarbon anode materials.

Notably, pin-type sand mills are used for grinding both LFP and siliconcarbon anode materials.

Pin-type sand mills feature high linear speed and transfer high kinetic energy to the grinding zirconia beads, making them suitable for highefficiency grinding of battery materials.At the same time, they impose higher requirements on the performance of zirconia beads: excellent wear resistance and low breakage rate.

Similarities and Differences in Grinding Processes for Cathode and Anode Materials

The grinding principle of zirconia beads is that the beads, driven by the sand mill, impact and shear the battery material particles to reduce particle fineness.Their applications in cathode and anode grinding each show distinct characteristics.
