Ketjen Black (SL-EC6) Powder, High-Conductivity Conductive Carbon Black Additive for Lithium-Ion Batteries

About this item

• Ultra-High Surface Area: BET surface area of 1,400 m²/g provides abundant conductive contact points with active material particles, enabling efficient conductive network formation at very low addition levels
• High-Structure Conductive Network: DBP absorption of 495 ml/100g (typical 480 ml/100g) reflects a highly branched aggregate structure, maintaining effective conductive pathways under high electrode compaction and supporting improved rate capability and cycle stability
• High Purity & Fine Particle Size: ash content ≤ 0.02 wt%, moisture ≤ 0.2 wt%, volatile matter ≤ 0.5 wt%, and 325-mesh pass rate ≥ 99.8%, promoting uniform slurry dispersion and consistent electrode coating quality
• Controlled Metallic Impurities: Fe ≤ 50 ppm (typical 50 ppm), Ni ≤ 2 ppm, and Co, Cr, Cu, Mn, V each < 1 ppm, meeting battery-grade purity requirements and minimizing the risk of self-discharge and internal short circuits
• Low Loading for Battery Applications: recommended addition level of 0.5-1.5 wt% for lithium-ion battery electrodes; can be combined with flake graphite (SL-G6 or SL-G15) to build a dual-conductive network for enhanced electrode performance
