Silicon-Carbon Anode Material Sand Mill

Silicon-carbon composite anode material

The trend toward larger screens and diversified functions in digital terminal products has imposed new demands on battery endurance. Currently, the gram capacity of lithium battery materials is relatively low, failing to meet the growing battery requirements of terminals.

Silicon-carbon composite material, as a type of future anode material, has a theoretical specific capacity of approximately4200mAh/g,Compared to graphite-based anodes.372mAh/gThe Chinese phrase "高出了" can be translated into English as **"exceeded by"** or **"higher than"**, depending on the context. For example: - 高出了10% → **exceeded by 10%** - 高出了平均水平 → **higher than the average** If you provide the full sentence, I can give a more precise translation.10more than doubled. Once industrialized, it will significantly enhance battery capacity. Currently, major material manufacturers are actively researching and developing silicon-carbon composite materials, such asBTRGe Xin Nano, Shanshan, Huawei, Samsung, etc. The main issues currently existing with silicon-carbon composite materials are:

1During charging and discharging, the volume expands and the liquid absorption capacity is strong.; 2The cycle life is poor. Currently, efforts are being made to address the above issues through methods such as silicon powder nanonization, silicon-carbon coating, and doping, and some companies have already made certain progress.

SPAdvantages of the series of shaftless, screenless vertical sand mills:

Shaftless seal: No worries about leakage, damage, or maintenance.

No screen: No clogging, no need to clean the screen or screen beads;

Ultra-fine grinding mediaΦ0.05-2.0mm, enabling nano-level ultra-fine grinding;

Efficient Grinding: The power is mainly used for effective grinding of large particles, with efficiency improved compared to horizontal machines.50%above;

Classification and Separation, Classification and Grinding Function: The role of centrifugal separation allows fine particles to be discharged from the grinding chamber with fewer grinding cycles, preventing over-grinding. Coarse particles cannot be discharged and are ground multiple times, even dozens of times, within the chamber, quickly becoming fine. The final product particles are highly uniform with a very narrow distribution.
