Nickel Phosphate (Ni₃(PO₄)₂): The High-Capacitance Supercapacitor Material, Now Manufactured in Indonesia

In direct electrochemical testing of Ni₃(PO₄)₂ coated onto Ni foam, using a three-electrode system in 1 M KOH electrolyte, a specific capacitance of 1,204.60 F/g was recorded at a current density of 1 A/g, a figure that far exceeds many MOF-based and conducting-polymer electrode materials for similar applications. Nickel Phosphate (Ni₃(PO₄)₂) is the nickel- and phosphate-based inorganic compound behind that performance, a combination of Ni²⁺ ions and phosphate (PO₄³⁻) groups forming a crystal lattice with multiple accessible nickel oxidation states useful for fast redox reactions.

Research labs in Indonesia have typically had to import transition-metal phosphate materials with high crystallinity and genuinely verified electrochemical performance. Both supercapacitor and photocatalytic performance depend heavily on how completely the crystal forms, not just on the simple chemical formula on paper. 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 Nickel Phosphate locally, with electrochemical testing run directly on every batch. Here's what Nickel Phosphate actually is, why its crystallinity matters, and where it's being used in research and industry today.

What Is Nickel Phosphate (Ni₃(PO₄)₂)?

Nickel Phosphate is built from Ni²⁺ ions bonded to phosphate (PO₄³⁻) groups, forming a crystalline inorganic compound that behaves as a wide-bandgap semiconductor. Unlike MOFs or conducting polymers that rely on an organic framework, Ni₃(PO₄)₂ is a purely inorganic compound, structurally simpler yet still showing strong electrochemical and photocatalytic activity thanks to its nickel redox couple.

Crystallinity is the biggest factor in Nickel Phosphate's performance, since crystallite size and single-phase purity directly affect the accessible electrochemical surface area as well as charge separation efficiency under light excitation. ITNANO's Nickel Phosphate is supplied at 99% purity, with a chemical formula of Ni₃(PO₄)₂ and a molecular weight of 366.023 g/mol, taking the form of a green powder. Its XRD pattern confirms the formation of single-phase Ni₃(PO₄)₂ with high crystallinity, with a crystallite size in the nanometer range of roughly 30 to 50 nm. UV-Vis results show a Tauc plot bandgap of 3.08 eV, indicating Ni₃(PO₄)₂ is a direct wide-bandgap semiconductor, while direct electrochemical testing recorded a specific capacitance of 1,204.60 F/g at 1 A/g.

Where Nickel Phosphate Is Being Used

Supercapacitor and battery electrodes

The 1,204.60 F/g specific capacitance at 1 A/g recorded on ITNANO's Nickel Phosphate places it among the most competitive materials for supercapacitor electrodes, drawing on the Ni²⁺/Ni³⁺ redox couple that stores charge through a pseudocapacitive mechanism. The same properties are also relevant for battery electrode applications that require high-capacity storage materials.

Catalysis and photocatalysis

The direct 3.08 eV bandgap confirmed through Tauc plot analysis makes Nickel Phosphate an attractive candidate for photocatalytic applications, where photon energy from UV light is sufficient to excite electrons across its bandgap and drive catalytic reactions at the material's surface. The Ni²⁺ sites within its structure also serve as catalytic centers for various chemical reactions.

Electrochemical sensing

Ni₃(PO₄)₂'s strong nickel redox activity also makes it useful as an active material for electrochemical sensors, drawing on changes in electrical signal as the material interacts with target analytes.

Pigments and optoelectronic materials

Nickel Phosphate's characteristic green color, combined with its semiconducting properties, gives this material additional potential as a pigment and as a component in optoelectronic materials, although these applications remain at an earlier exploratory stage compared to its use in electrochemistry.

Why Source Nickel Phosphate Locally

Ni₃(PO₄)₂'s crystallinity and crystallite size are properties sensitive to synthesis conditions, and a batch with less perfect crystals will deliver capacitance well below 1,204.60 F/g even though its chemical formula stays exactly the same. This kind of performance difference isn't always visible from the powder's green color. ITNANO, established by the Titian Research Group's NRE Lab, manufactures Nickel Phosphate domestically and tests its electrochemical performance directly on every batch, giving labs in Indonesia a material whose performance is genuinely verified, not just assumed from a spec sheet.

Whether you're developing supercapacitor or battery electrodes, researching photocatalytic applications, formulating electrochemical sensors, or working on pigment and optoelectronic applications, Nickel Phosphate gives you a crystallinity and electrochemical performance that a distant supplier can't guarantee after shipping, without the import wait.
