Dual-power Sand Mill Enables Grinding Of Silicon Carbon Anode Materials

In lithium batteries, the negative electrode material serves as a carrier of lithium ions and electrons during the charging process and assumes the function of storing and releasing energy. It accounts for about 8% of the manufacturing cost of lithium batteries. The silicon anode has the highest theoretical mass specific capacity (3580mAh/g at room temperature) and abundant resource reserves, and can provide channels for lithium ions to be inserted and extracted from all directions. The lithium insertion potential is high and the fast charging performance is excellent, avoiding the need for The dendrite problem that is difficult to overcome in lithium anodes has the characteristics of high safety and high capacity. It is considered to be the next generation anode material and has become the most popular in the industry.

From a product perspective, the technological iteration direction of silicon-carbon anodes basically revolves around preventing SEI film formation and reducing expansion. In the preparation process of silicon-carbon anode, nano-silicon particles need to be prepared first, and the outermost layer is coated with carbon to form a shell-core structure, which is the final finished silicon-carbon anode. The current mainstream production process is mainly grinding.

Core advantages of dual power sand mill

0.05mm media can be used for stable grinding and dispersion;

Unique centrifugal technology avoids clogging and ball leakage;

Special jacket cooling system can cool quickly;

The grinding chamber is designed with all-ceramic materials, and the materials are pollution-free;

Automated PLC control system to create an intelligent factory.

As a silicon-carbon material that will be widely used in negative electrodes in the future, there are even higher requirements in terms of production effects and precision. Usually the grinding fineness of silicon carbon must be less than 100nm, and problems such as ball leakage and material blockage are often encountered during the production process.

The grinding cavity of Yushun intelligent dual-power sand mill is designed with all-ceramic materials. The advanced mesh-less separation can stably use grinding media as low as 0.05mm, with high efficiency, good grinding effect and narrow particle size distribution. It effectively solves the problems of ball leakage and material clogging, and is an effective solution for grinding nanomaterials.

Yushun intelligent dual-power nano sand mill is mainly used in high-end nanomaterials such as silicon carbon anodes and other high-end nanomaterials to achieve high-efficiency ultra-fine grinding, empower efficient production, and contribute to the development of high-end nanomaterials.
