Overview
Ultra-high-surface-area activated carbon engineered for electric double-layer capacitors (EDLCs) and electrochemical capacitors. Features a 3D interconnected mesopore network with precisely controlled pore diameter, balancing ion-accessible surface area with rapid transport kinetics. Comprehensive batch-level certification ensures electrode manufacturers maintain consistent slurry rheology and coating quality across production campaigns.

Key application areas
- Supercapacitors (EDLCs) for grid frequency regulation
- High-power energy storage electrodes
- Regenerative braking systems
- Pulse-power military and aerospace applications
- Electrochemical capacitors requiring long cycle life
Electrochemical Stability
- Ultra-low metal impurities: aluminium and iron held below 50 ppm; nickel and copper below 5 ppm. This prevents parasitic side reactions that degrade cycle life, supporting over 100,000 charge/discharge cycles.
- PSD-16: BET >1600 m²/g and pore volume >0.6 cm³/g for standard high-power applications.
- PSD-18: BET >1800 m²/g and pore volume >0.8 cm³/g for maximum energy density in premium capacitors.
- Narrow particle distribution and high tap density optimize electrode packing and reduce binder demand.
- Batch-level BET and pore-distribution certification ensures consistent slurry rheology—critical for defect-free electrode coating.
