①Multi-layer reactor design: Adjust reactor angles and optimize gas distribution to achieve uniform silicon deposition； ②Temperature control to avoid local variation: Precisely regulate temperature during deposition to prevent localized overheating, which may lead to non-uniform deposition.

①Synergistic effect of acetylene for improved coating integrity: First, form an initial coating via vapor deposition, followed by acetylene treatment to enhance carbon coverage；② Optimization of coating process parameters: Adjust temperature, duration, and atmosphere conditions during coating to ensure uniform decomposition and deposition of the carbon precursor on silicon particles, forming a dense and stable carbon layer；③ Pre-treatment and purity control of carbon precursors: Employ physical activation of the carbon precursor to enhance reactivity and interfacial bonding, and control precursor particle size and purity to prevent impurities from adversely affecting the carbon coating quality.

① Fluidized bed technology to overcome deposition non-uniformity: Place the carbon matrix in a fluidized particle bed; the flowing gas creates a liquid-like state, enabling uniform exposure of particles to silane gas and achieving homogeneous nano-silicon deposition；② Intelligent batching system: Automatically adjust ingredient ratios to eliminate batch-to-batch variability and uneven mixing.

① Optimization of collection system: Minimize material retention and loss during collection；② Optimization of reaction conditions: Precisely control gas flow and reaction time to improve carbon source utilization and reduce residual raw materials.

Continuously supply inert gas during the fluidized bed deposition process to maintain an inert environment. Simultaneously monitor oxygen levels in real time; if abnormal fluctuations occur, trigger timely alerts and adjustments to ensure a stable and controllable deposition process.
