95 ceramic beads Zirconia Grinding Media For Lithium battery material cathode material
95 ceramic beads Zirconia Grinding Media , also called zirconium beads, 95 zirconium beads, yttrium stabilized zirconia beads, zirconia balls, zirconia ceramic balls, Zirconia Ceramic Grinding Media, etc.
Use micron/sub-nanometer zirconia powder as raw material, sintered by medium-high temperature by sintering method. It has good spherical gloss, high density, high hardness, low abrasion and high grinding efficiency.
It is the high quality grinding media, widely used for grinding and dispersion of Lithium battery material cathode material like
Lithium manganese oxide, lithium cobalt oxide, lithium nickel cobalt manganese oxide materials.

95 Yttrium stabilized ceramic beads is widely used for grinding of Lithium battery material cathode material, like Lithium manganese oxide, lithium cobalt oxide, lithium nickel cobalt manganese oxide materials, ternary cathode material.
The particle size and particle size distribution of the material have a direct impact on the electrochemical performance of the material. The reduction of the material particles increases the specific surface area, which increases the contact area between the electrode material and the electrolyte, improves the reaction activity of the material, and improves the electrochemical performance of the material.
Therefore, Usually use size 0.2mm, 0.3mm, 0.4mm.
Ball mill is usually used to mill the raw materials.
In the ball milling process, the material and the grinding medium (zirconia beads 0.3mm) inside the machine are stirred by the high-speed rotating disperser, so that the particles in the material and the zirconia beads collide and rub against each other, thereby causing The material can be evenly refined. In order to obtain the ternary cathode material with uniform particle size distribution and small particles, we explored the ball milling process parameters and found the optimal process parameters.
The best ball milling process parameter setting is: 2000 r·min-1, and the ball milling time is 50 min.
