Carbon Black Ketjen Black ECP-600JD: The Conductive Additive Behind Nearly Every Commercial Lithium-Ion Battery, Now Manufactured in Indonesia

Ketjen Black has a nanostructure resembling a highly branched, hollow grape cluster, giving it a surface area of up to 1,400 m²/g, more than twenty times higher than standard conductive carbon black, which typically sits around 60-70 m²/g. This unique structure is exactly what makes Ketjen Black one of the most efficient conductive additives known in the battery industry: only a very small amount needs to be added to form a conductive network connecting active material particles throughout an electrode, far more economical than conventional carbon black at the same loading.

Research labs in Indonesia have typically had to import Ketjen Black with a genuinely preserved porous structure. This branched, hollow structure is fragile and can be crushed under pressure or rough handling during long-distance shipping, reducing porosity and conductive network efficiency. That's starting to change.

ITNANO (CV. Inovasi Teknologi Nano), based at the NRE Lab in Medan, is Indonesia's first private nanomaterials research startup manufacturing Ketjen Black ECP-600JD locally. Here's what Ketjen Black actually is, why its structure matters so much, and where it's being used in research and industry today.

What Is Ketjen Black ECP-600JD?

Unlike conventional carbon black, which forms solid particles, Ketjen Black is built from hollow carbon nanospheres fused into a highly branched aggregate. This hollow, branched structure is exactly what gives Ketjen Black far higher porosity and surface area than ordinary carbon black, along with a more efficient conductive network even when used in small amounts.

The condition of its branched structure is the biggest factor in Ketjen Black's performance, since damage to this structure directly reduces its porosity and its ability to form a conductive network. ITNANO's Ketjen Black is supplied at above 99.5% purity, with a specific surface area of 1,400 m²/g, a pore volume (DBP) of 440-510 ml/100 g, a resistivity of 0.3-1 Ohm·cm, and an ash content of only 0.05%. Its iodine absorption value ranges from 440-510 mg/g, with a particle size of 200 mesh (>98 wt.%) and 325 mesh (>80 wt.%), and a moisture content below 1%. Compared to Super C-65 carbon black, Ketjen Black offers higher electrical conductivity and a far more porous morphology.

Where Ketjen Black Is Being Used

Conductive additive for battery electrodes

This is Ketjen Black's most common application: as a conductive additive in lithium-ion battery electrodes and other battery types, linking individually less conductive active material particles into a continuous electrical network throughout the electrode.

Fuel cells

Ketjen Black's high surface area and porosity also make it widely used in fuel cell electrodes, supporting even catalyst distribution along with an efficient electron conduction pathway.

Supercapacitors

Ketjen Black is used as a conductive additive in supercapacitor electrodes, boosting overall electrode conductivity without sacrificing the capacity of the main active material.

Sensors

Beyond energy applications, Ketjen Black is also used as an active material in various types of sensors, drawing on its high conductivity and large surface area.

Why Source Ketjen Black Locally

Ketjen Black's hollow, branched aggregate structure is a physically fragile property, capable of being crushed under pressure or rough handling during long-distance shipping, reducing its porosity and conductive network efficiency even though it remains chemically the same. ITNANO, established by the Titian Research Group's NRE Lab, manufactures Ketjen Black ECP-600JD domestically with consistent quality control, giving labs in Indonesia a material whose porous structure is genuinely preserved from the moment it arrives.

Whether you're formulating lithium-ion battery electrodes, developing fuel cells, researching supercapacitor electrodes, or working on sensor applications, Ketjen Black ECP-600JD gives you a pore structure and conductive performance that a distant supplier can't guarantee after shipping, without the import wait.
