The manufacturing chain begins with high-purity silicon-based anode materials. Depending on performance targets, producers utilize silicon oxide (SiOx), nano-silicon powders, silicon-carbon composites, or engineered silicon-dominant structures. Material purity frequently exceeds 99.9%, while particle-size control is maintained at micron or sub-micron levels to improve electrochemical stability and reduce expansion-related degradation.

The production route generally includes:

• Silicon material synthesis and purification
• Silicon-carbon composite preparation
• Anode slurry formulation
• Electrode coating and drying
• Cell stacking and pouch assembly
• Electrolyte filling and formation cycling
• Aging, testing, and qualification

Among these stages, electrode formulation and formation cycling represent the most technically demanding operations.
