High Purity Acetylene Black Battery Conductive Agent Powder for Energy Storage and Polymer Applications

Product Overview

This high-purity acetylene black is a specialized conductive carbon additive engineered to establish robust, continuous electronic transport networks in electrochemical systems and advanced industrial materials. Synthesized through the controlled thermal decomposition of unsaturated hydrocarbon feedstock, the resulting carbon material features an exceptional primary particle structure that prevents electrical isolation within active material matrices. By bridging the micro-gaps between poorly conductive metal oxide particles or polymer chains, this additive drastically reduces bulk impedance while enhancing dynamic charge transfer.

Designed primarily for high-demand energy storage devices—including lithium-ion positive electrodes, secondary battery cells, and primary dry batteries—the material also serves as an essential functional filler for anti-static elastomers, radio components, and engineered plastics. Its balanced surface area and optimized particle morphology allow formulation engineers to achieve low percolation thresholds without compromising slurry rheology or mechanical integrity. Whether dispersed into cathode slurries or compounded into thermoplastic matrices, the powder ensures uniform distribution and stable electrical paths.

Manufactured under stringent quality control protocols, this conductive carbon additive provides exceptional consistency in particle size distribution, moisture suppression, and trace impurity management. The material is chemically inert across wide potential windows and insoluble in water, acids, and alkalis, offering dependable stability in harsh electrochemical and chemical environments. Procurement teams and battery researchers can rely on its predictable electrochemical behavior to improve cell capacity retention, reduce internal resistance, and maintain operational stability across extended cycling schedules.

Key Features

• Superior Intrinsic Electronic Conductivity: Exhibiting an ultra-low specific resistivity of 1.4 Ω·m, this conductive powder rapidly establishes low-resistance pathways throughout the electrode, effectively eliminating localized polarization and accelerating high-rate electron discharge.
• Optimized Specific Surface Area Architecture: With a Statistical Thickness Surface Area (STSA) of 106 ± 9 × 10² m²/kg and an iodine absorption value of 98 mg/g, the powder provides an ideal balance between conductive contact area and manageable slurry binder consumption.
• Exceptional Electrolyte Absorption and Retention: Featuring an acid absorption value of 4.4 cm³/g and an apparent specific volume of 16.5 cm³/g, the material absorbs and retains liquid electrolyte efficiently, facilitating ion migration and preventing dry spots within high-density pressed electrodes.
• Ultra-Low Impurity Profile: Engineered with a low ash content of just 0.06% and a minimal coarse particle fraction of 0.009%, this material prevents microscopic short circuits, dendrite nucleation, and parasitic chemical reactions within battery cells.
• High Thermal and Chemical Inertness: Unaffected by concentrated acids, alkalis, and organic solvents, the carbon structure maintains physical and chemical integrity throughout aggressive battery cycling and high-temperature polymer processing.
• Controlled Surface pH Chemistry: A neutral-to-slightly-acidic pH value of 5.8 ensures broad compatibility with standard aqueous and non-aqueous battery binders (such as PVDF and CMC/SBR), preventing unwanted slurry gelling or premature sedimentation.
• Strict Moisture and Volatile Control: With a heating loss rating of ≤ 0.08%, the powder minimizes residual moisture introduction into moisture-sensitive battery chemistries, preventing premature electrolyte degradation and gas generation.
• High Tinting Strength and Opacity: Beyond its electrochemical functionality, the material exhibits intense jetness, neutral undertones, and outstanding hiding power, functioning as a stable, non-fading black pigment for specialty industrial compounds.
