Preparation of slurry

In the lithium battery industry, strong mixers are commonly used for preparing slurries for positive and negative electrode materials, mixing electrolyte slurries, and surface coating of battery materials. Among them, the preparation of slurry for positive and negative electrode materials is one of the important links in the production of lithium batteries.

For the preparation of slurry for positive and negative electrode materials of lithium batteries, a tilting strong mixer is usually used. In this device, various raw materials such as lithium salts, polymers, and carbon black can be added, and they can be fully mixed through strong friction and shear forces. Meanwhile, the inclined strong mixer has the characteristics of high mixing efficiency, low energy consumption, and convenient operation, which can greatly improve production efficiency.

In addition, during the surface coating process of battery materials, a strong mixer is also a very important equipment. The surface coating is usually carried out by the sol gel method, that is, the surface of the material is coated with a layer of gel containing solid particles. A powerful mixer can mix coatings and particles evenly, resulting in uniform coatings, strong adhesion, and good electrochemical performance.

In summary, in the lithium battery industry, a powerful mixer is a very important equipment that can provide efficient and accurate support for the preparation and coating of battery materials.

Process technology

Sinotech has improved the preparation of lead paste through its unique three-dimensional turbulent vacuum technology. Sinotech will optimize equipment configuration based on customer needs through its modular system.

Sinotech Lithium Battery Mixer is a closed system with controllable mixing and reaction processes.

Principle of mixing

The excellent mixing effect comes from:

1. A rotating mixing disc, a high-speed rotating mixing tool that directly carries materials through centrifugal motion. Logistics that can generate high-speed differences.

2. A tilted rotating mixing disc. Connect a fixed, double acting wall scraper to ensure significant vertical circulation of material.

3. Double acting wall scraper to prevent material from sticking to the wall and bottom of the disc. And accelerate unloading at the end of the mixing cycle.

Technical reliability and safe operation

Acids and additives are quickly and uniformly dispersed:

The fully automatic needle penetration control supported by Sinotech vacuum technology ensures consistent fluidity. At the same time, the self regulating sealing of the discharge door can ensure the optimal sealing protection of the mixing disc.
