The cathode material plays a core role in lithium-ion batteries. Lithium-ion batteries have advantages such as high operating voltage and high energy density, and are widely used in 3C devices, electric vehicles, and other fields. The cathode material accounts for more than 40% of the total cost of lithium batteries, and its performance directly affects various performance indicators of lithium batteries, such as energy density, safety, and cycle life.

Vertical grinders are essential in the processing of cathode materials. Currently, the main types of cathode materials for lithium-ion batteries are layered structure, spinel structure, and olivine structure. These cathode materials often require processes such as mixing, calcination, grinding, and sieving during preparation. Among these, the grinding step is crucial, and vertical grinders play an important role in this step.Taking lithium manganese oxide as an example, its main component is spinel-type lithium manganese oxide, which can be used as a cathode material for lithium-ion batteries. The mainstream industrial process currently uses high-temperature solid-phase method to prepare lithium manganese oxide, with basic production processes including mixing, calcination, grinding, sieving, and product. In this process, vertical grinders can finely grind the calcined materials, resulting in larger specific surface area, more uniform mixing, and narrower particle size distribution.

In addition, the powder grinding step is indispensable in the manufacturing process of all-solid-state batteries.

Vertical grinder"Cell mill"shows significant application value in the field of solid-state batteries. Itsunique vertical designfeatures nano-level efficient grinding,usingzirconia beads to achieve nano-level grinding, resulting in uniform particle size and narrow distribution; it uses a permanent magnet motor direct drive, which is more energy-efficient than a three-phase asynchronous motor by more than 20%.The rotor structure design of the vertical grinder is unique, enhancing shear force to achieve nano-level grinding, greatly improving grinding efficiency. Through high-frequency reciprocating stirring

, impact, and shear actions, the ground samples are more fully and uniformly processed, with better sample reproducibility and no cross-contamination. It can process a large number of samples in a short time, greatly improving production efficiency.Meeting the stringent requirements of the high-end market for material quality,and satisfying various personalized needs of customers.，满足客户的各种个性化需求。
