GN-520B Supercapacitor Active Carbon – High Surface Area 2000 m²/g for EDLC Electrodes
GN-520B is a premium grade activated carbon specifically engineered for supercapacitor (electric double-layer capacitor) applications. With an ultra-high specific surface area of 2000 ± 100 m²/g and optimized pore structure (2.0–2.2 nm), this material delivers exceptional capacitance and rate performance in organic electrolyte systems.
Key Features:
- High Specific Surface Area: 2000 ± 100 m²/g provides abundant charge storage sites.
- Optimized Pore Size: 2.0–2.2 nm mesopores facilitate rapid ion transport and high power density.
- Fine Particle Size: D50 = 5 ± 1 μm ensures good dispersibility and electrode uniformity.
- High Purity: Carbon content >95%, ash <0.07%, and total metal impurities <1000 ppm (ICP) guarantee minimal side reactions.
- Excellent Capacitance: Organic electrolyte capacitance >130 F/g and >60 F/cc.
- Consistent Quality: Controlled pH (5.5–8.0) and iodine adsorption (2000 ± 100 mg/g) confirm reliable performance.
Applications:
- Electric double-layer capacitor (EDLC) electrodes
- Hybrid supercapacitor formulations
- Energy storage research and development
- High-power density devices
