The experimental intensive mixer for positive electrode materials of lithium batteries is a device used for mixing positive electrode materials on a laboratory scale to ensure uniform distribution of materials, which is suitable for small-batch research and development and production.

Tilted strong intensive mixer

Working principle: Through the tilted rotating mixing disk, a fixed double-acting wall scraper is connected. The rotating disk directly carries the material for centrifugal motion to generate high-speed differential flow. The wall scraper prevents the material from adhering to the wall and bottom of the disk, while ensuring significant vertical circulation of the material.

Advantages: high mixing efficiency, low energy consumption, easy operation, and can effectively overcome the unevenness of lithium battery materials caused by different characteristics such as particle size, density, shape, viscosity, etc. It can be configured with vacuum, heating, cooling and other functions to reduce material oxidation and degradation and avoid bubble formation.

Applicable scenarios: Suitable for slurry mixing of lithium battery positive electrode materials such as ternary, lithium iron phosphate, lithium cobalt oxide, lithium manganese oxide, etc., ranging from 1 liter to 50 liter models for small laboratories to 100 liters to 2000 liter models for large production lines.

High-speed intensive mixer

Working principle: The shear force generated by the high-speed rotation of the stirring paddle drives the powder material to rotate at high speed in the cylinder, so that different materials can be depolymerized and evenly mixed.

Advantages: It has the advantages of high efficiency, low cost, simple structure, etc. It is a commonly used dry intensive mixer in the positive electrode material industry.

Applicable scenarios: It is suitable for dry mixing of components such as precursors, lithium sources, doping additives, etc. to ensure the consistency of the solid-phase sintering reaction.
