Coin Cell Casing CR2032: The Battery Assembly Component for Lab Research, Now Available in Indonesia

Testing any new battery material, whether it's an electrode, an electrolyte, or a separator, calls for a standardized cell format that can be reproduced reliably, and that's where the CR2032 coin cell comes in. This format is used widely across battery research labs worldwide because it's compact, requires only a small amount of material, and delivers results that can be compared consistently between labs. But that testing performance depends heavily on something that's easy to overlook: the casing components themselves. Precise dimensional tolerance and a consistently reliable sealing gasket determine whether internal cell pressure holds, whether electrolyte leaks or gets exposed to air, and ultimately whether the electrochemical data you get actually reflects the material being tested, rather than an artifact of a leaking cell or imprecise housing.

Research labs in Indonesia have typically had to import coin cell casing with genuinely verified dimensional tolerance and sealing quality. That's starting to change.

ITNANO (CV. Inovasi Teknologi Nano), based at the NRE Lab in Medan, provides direct access to CR2032 coin cell casing in Indonesia, complete with verifiable official specifications. Here's what coin cell casing actually is, what components make it up, and where it's being used in battery research today.

What Is Coin Cell Casing?

Coin cell casing is a set of mechanical components that encloses and seals an electrode-separator-electrolyte stack into a single, sealed coin-shaped battery cell. A complete CR2032 casing set consists of a top cap and bottom case (two metal parts that serve as both terminals and the outer housing of the cell), a sealing gasket that electrically isolates the two terminals while preventing electrolyte leakage and the ingress of air or moisture, and a spring and spacer on the inside that maintain consistent contact pressure across the electrode layers once the cell is crimped shut. Once the electrode stack and electrolyte are loaded in, the whole assembly is closed using a crimper to produce a sealed, test-ready cell.

ITNANO's coin cell casing follows the standard CR2032 format at 20 mm diameter × 3.2 mm height, fitted with a PP (polypropylene) sealing gasket, a 15.8 × 0.5 mm spacer, and a 15.4 × 1.3 mm spring. Casing is available in two stainless steel grades, SS316 and SS304, so labs can choose based on the corrosion resistance and budget their testing requires.

Where Coin Cell Casing Is Being Used

Lithium-ion battery research and development

This is coin cell casing's most common use: as the lab-scale cell housing for evaluating new cathode or anode active materials, electrolyte formulations, and separators, before those materials move on to testing in larger cell formats.

Half-cell and full-cell electrochemical characterization

Coin cells assembled with precision casing are used for standard electrochemical tests such as cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and galvanostatic charge-discharge cycling, where consistent internal cell pressure and sealing integrity strongly affect the repeatability of results across samples.

Lab-scale supercapacitor electrodes

The same casing format is also used to assemble research-scale supercapacitor cells, enabling evaluation of the capacitance and cycling stability of high-surface-area electrode materials in a compact housing that's easy to disassemble for post-test analysis.

Why Get Genuine Coin Cell Casing from ITNANO

Inconsistent dimensional tolerance in the casing, spring, or spacer can cause the crimping process to produce a cell that isn't sealed properly, either too loose so electrolyte leaks out or gets exposed to air, or too tight so the separator gets damaged during crimping. ITNANO provides coin cell casing with directly verifiable dimensional specifications, giving labs in Indonesia certainty that every cell they assemble has the same mechanical condition from one test to the next.

Casing is also available in two grades, SS316 and SS304, so labs can pick based on what a given test needs: SS316 contains molybdenum, which gives it better corrosion resistance against more aggressive electrolytes, while SS304 is the more economical option for routine testing. Whether you're testing new cathode or anode materials, developing an electrolyte formulation, or assembling lab-scale supercapacitor cells, ITNANO's coin cell casing gives you dimensional certainty and sealing quality without the import wait.
