Conductive Carbon Black Super C65 Battery Grade
CAS Number: 1333-86-4
Super C65 carbon black is a high-surface-area (BET ~62 m²/g), high-structure conductive additive widely used in NMC, NCA, LCO, and LFP cathode electrodes. Its branched particle network creates efficient electron conduction pathways at low loadings (1–3 wt%), improving rate capability and reducing ohmic resistance in lithium-ion battery electrodes.

Applications
- NMC/NCA/LFP cathode conductive additive (1–3 wt%)
- Graphite and silicon anode conductive additive
- LTO anode electrode formulation
- Solid-state battery composite electrode
- Supercapacitor electrode carbon additive
Key Features
- Moderate BET (~62 m²/g) balances conductivity and binder demand in cathode formulations
- High structure (DBP ~185 mL/100g) forms percolating networks at low filler loading
- Low ash and magnetic particle content (<10 ppm metal) for premium cell quality
- Available in pellet form to reduce dust and improve handling safety in manufacturing
