Advantages

1. Ultra-high conductivity, significantly reducing battery internal resistance

Produced using specialized processes such as the acetylene black method or the furnace method, this carbon black features a fine primary particle size (30–50 nm) and a high specific surface area of 60–80 m²/g, forming a highly developed chain-like structure (DBP absorption value ≥ 300 ml/100 g).

Even a minimal addition (only 0.5%–1.5% by weight) is sufficient to construct an efficient three-dimensional conductive network within the electrode, reducing the resistivity of lithium-ion battery electrodes by more than 50% and enhancing rate discharge performance and cycle stability.

2. Ultra-low metal impurities, ensuring battery safety and longevity

Strictly controlled levels of magnetic contaminants such as Fe, Ni, Cu, Zn, and Cr ensure a total metal content of ≤ 20 ppm and a maximum metal particle size of ≤ 150 μm per particle.

This prevents metal impurities from puncturing the separator or catalyzing electrolyte decomposition, effectively reducing the risks of self-discharge, micro-short circuits, and thermal runaway, thereby meeting the high safety standards for power and energy storage batteries.

3. Excellent Dispersibility, Enhancing Slurry Processing Efficiency

The carbon black surface has been modified to achieve a balance between oil- and water-loving properties, ensuring high compatibility with common binders such as PVDF, SBR, and CMC, as well as solvents like NMP and deionized water.

It disperses uniformly without the need for prolonged high-speed stirring, reducing agglomerate formation. After coating, the electrode surface is smooth and free of particle protrusions, improving coating yield and reducing equipment energy consumption.

4. High Purity and Low Oil Absorption Value, Supporting High Energy Density Design

Ash content ≤ 0.1% and moisture content ≤ 0.5% prevent the introduction of additional side reactions.

A moderate oil absorption value (DBP 240–280 ml/100g) ensures conductivity while minimizing excessive absorption of binder and electrolyte, thereby allowing for a higher active material ratio and helping batteries achieve an energy density of ≥ 260 Wh/kg.

5. Stable batch consistency, suitable for large-scale continuous production

Full-process online particle size monitoring and magnetic separation for iron removal ensure that each batch is accompanied by a Certificate of Analysis (COA) report detailing particle size distribution (D50 40–60 μm), resistivity, and impurity content.

Flexible packaging options: 10 kg moisture-proof paper bags or 500 kg bulk bags, lined with an aluminum foil moisture barrier to prevent moisture absorption and caking during transportation and storage.
