Overview
Coconut-shell-derived porous carbon precursor for silicon-carbon composite anodes. Manufactured through steam activation and special-process washing to achieve higher purity porous materials. The extensive micropore network provides the ideal void space for nano-silicon expansion, while tight particle-size distribution ensures uniform electrode coating without slurry segregation. Suitable for heterogeneous catalyst carriers, silicon-carbon anode precursors, and electrochemical energy storage systems.

Key application areas
- Lithium-ion battery silicon-carbon anodes (3C electronics, EV powertrains, grid storage)
- Heterogeneous catalyst carriers
- New energy and electrochemical fields
Batch-Level Consistency
- Total pore volume tolerance ±0.03 cm³/g eliminates the "consistency risk" that causes cell capacity fade curves to diverge between batches.
- Ultra-low contamination: ash below 0.3% and magnetic matter below 2 ppm prevent electrolyte decomposition catalyzed by trace metals (Fe, Ni, Cu).
- Proven supply chain: already in mass shipment to tier-one anode manufacturers with 2026 volume exceeding one thousand tonnes.
- Biomass-derived feedstock supports renewable material sourcing goals.
