Overview
Resin-based porous carbon precursor delivering higher purity and more uniform pore architecture than biomass alternatives. Manufactured from synthetic resin materials through water vapor activation and special-process washing to achieve higher purity porous materials. The controlled activation-carbonization curves eliminate natural feedstock variability, making this the preferred choice for electrode manufacturers running continuous coating lines that cannot tolerate batch-to-batch drift.

Key application areas
- Premium lithium-ion silicon-carbon anodes
- High-purity heterogeneous catalyst carriers
- Advanced battery research and pilot lines
- New energy sources of silicon-carbon anode precursors and electrochemical fields
Synthetic Precision
- Micropore volume ratio 86±2%—tighter distribution than coconut-shell grades—ensures predictable silicon loading per batch.
- Total pore volume 0.85–1.0 cm³/g and BET 1850–2050 m²/g provide maximum buffer space for silicon expansion.
- Resin precursor eliminates natural biomass variability, delivering gigafactory-ready consistency for high-volume electrode manufacturing.
- Higher purity base material reduces acid-washing intensity, preserving more native pore structure.
