Nickel Foam (0.55 mm & 1.5 mm): The 3D Current Collector Behind Thousands of Supercapacitor and Catalyst Papers, Now Available in Indonesia

Open up a research paper on supercapacitor electrodes or oxygen evolution reaction (OER) catalysts, and chances are you'll find an SEM image of the active material grown directly on a silvery, porous surface, nickel foam. This 3D porous substrate has become the standard choice in thousands of research papers because it allows active material to be grown directly on its surface without a binder, eliminating the extra contact resistance that typically arises when material is coated via conventional slurry processing onto a flat current collector. ITNANO's Nickel Foam is available in two thickness options, 0.55 mm and 1.5 mm, each suited to different research needs.

Research labs in Indonesia have typically had to import nickel foam with genuinely consistent porosity and purity. That's starting to change.

ITNANO (CV. Inovasi Teknologi Nano), based at the NRE Lab in Medan, provides Nickel Foam for electrode research and development in Indonesia. Here's what nickel foam actually is, why thickness selection matters, and where this material is being used in research today.

What Is Nickel Foam?

Nickel foam is an open-cell, three-dimensional porous metal structure, made by coating nickel onto a polymer foam skeleton that is then removed through burnout, leaving behind a porous nickel network with very high porosity. This structure is exactly what makes nickel foam superior to conventional flat metal current collectors: its specific surface area is far greater for active material loading, while its interconnected pore network allows electrolyte to penetrate deep into the electrode.

ITNANO's Nickel Foam has a nickel purity above 99.9%, a PPI (pores per inch) of 110 ± 5, an average pore size of 0.2 ± 0.05 mm, an open-cell rate above 98%, and a porosity above 97%, with a sheet size of 10 × 20 cm (200 cm²). It's available in two thickness options: 0.55 mm for applications prioritizing low internal resistance and space efficiency, and 1.5 mm for applications requiring higher active material loading capacity per unit area.

Why Does Thickness Choice Matter?

Nickel foam thickness isn't just a preference, it's a real trade-off in electrode design. Nickel Foam 0.55 mm provides a shorter ion diffusion pathway and lower internal resistance, suited to high-rate performance testing or space-constrained coin cell applications. Meanwhile, Nickel Foam 1.5 mm offers far greater pore volume per unit surface area, allowing higher active material loading, relevant for research aiming to approximate the mass loading conditions found on industrial-scale electrodes.

Where Nickel Foam Is Being Used

Supercapacitor and battery electrode substrates

This is nickel foam's most common application: as a current collector and direct growth substrate for active material on supercapacitor and battery electrodes, eliminating the need for the binders and additional conductive additives typically used in conventional slurry-based electrodes.

Water electrocatalysis (OER and HER)

Nickel foam is also the standard substrate for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) electrocatalyst research in water splitting, where catalysts are grown directly on its surface to maximize contact area with the electrolyte while taking advantage of nickel's high conductivity as an electron transport pathway.

Why Source Nickel Foam from ITNANO

Consistency in porosity, pore size, and nickel purity is a critical factor when nickel foam is used as a direct growth substrate, since small variations in pore structure can affect how evenly active material deposits and, ultimately, the consistency of electrochemical measurement results across samples. ITNANO provides Nickel Foam with directly verifiable specifications in two thickness options, giving labs in Indonesia a consistent electrode substrate without needing to wait through a long import process.

Whether you're developing direct-growth supercapacitor or battery electrodes, researching OER/HER catalysts for water splitting, or need a substrate with high mass loading or low resistance, ITNANO's Nickel Foam gives you a porosity and purity consistency that a distant supplier can't guarantee after shipping, without the import wait.
