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.
