Fluidized bed

The vapor deposition silicon carbon fluidized bed is a core equipment designed specifically for surface coating of silicon carbon negative electrode materials in lithium batteries. By using fluidization technology and chemical vapor deposition (CVD), silicon or silicon carbide nanolayers are uniformly deposited on the surface of porous carbon particles, significantly improving the conductivity, cycling stability, and energy density of the negative electrode.

Product Highlights

Dynamic fluidization design
Particles are fully suspended, resulting in a 50% increase in gas-solid contact efficiency and a coating thickness deviation of less than 5%.
Three dimensional porous structure
Forming carbon skeleton composite silicon material, reducing cyclic expansion rate by 30% and extending battery life by 20%.
One way conversion rate of 99%
Silane utilization rate far exceeds Siemens method, reducing energy consumption by 40%.
Modular production capacity
Supports a batch processing capacity of 10-150 kg, operates continuously for 24 hours, and is suitable for pilot scale production of 100 kg to mass production of 100 tons.
Inert atmosphere protection
Oxygen index ≤ 50 ppm to prevent silicon oxidation and denaturation, ensuring material purity.
Multi purpose
Compatible with multi-layer coating of silicon carbon negative electrode, silicon carbide quantum dots, nuclear fuel particles, etc.
