This coin cell case set is designed for electrochemical systems operating above 4.5 V and has been verified to exhibit no side reactions between -0.5 V and 5.0 V. The components must be kept free of oils, burrs, and contaminants to ensure reliable sealing and long-term cycling stability.

  • Voltage Window Constraint: The aluminum-clad positive case maintains electrochemical stability between -0.5 V and 5.0 V, preventing side reactions in high-voltage battery systems.
  • Cleanliness Requirement: The components are supplied oil-free and burr-free and must be stored and handled in a clean environment to preserve sealing integrity and prevent contamination.

How does the aluminum-clad coating on the positive case improve high-voltage performance compared to standard stainless steel cases?

The 5–10 μm aluminum-clad coating (adhesion ≥5B) provides electrochemical stability in the -0.5 V to 5.0 V range without side reactions, making it ideal for cells operating above 4.5 V. Standard stainless steel cases risk corrosion or metal ion contamination at such high potentials, which the Al-Clad design mitigates while maintaining low contact resistance (volume resistivity ≤3×10⁻⁸ Ω·m).

Are these Al-Clad CR2032 coin cell cases compatible with standard coin cell crimping tools?

Yes, the cases are dimensionally identical to standard CR2032 hardware with a tolerance of ±0.02 mm, ensuring full compatibility with industry-common crimpers. The 316L/304 stainless steel negative case provides the required mechanical strength for sealing pressures up to ≥6 MPa, while the aluminum-clad positive case maintains structural integrity during crimping.

What pre-treatment or cleaning is required before using the Al-Clad coin cell cases inside an argon glovebox?

No pre-treatment is required. Each set is shipped oil-free, burr-free, and impurity-free after 100% dimensional and sealing inspection, allowing direct transfer to an argon glovebox for immediate battery assembly without additional cleaning or drying steps.

The ATOMFAIR CR2032 Al-Clad Coin Cell Case Set is designed for high-voltage battery research (>4.5 V), featuring an aluminum-clad positive case on 316L/304 SS substrate with 5-10 μm coating, paired with 316L/304 SS negative cases and 304 SS spacers/springs, offering ±0.02 mm dimensional tolerance and verified electrochemical stability from -0.5 V to 5.0 V.

Positive

  • High-voltage electrochemical stability: The aluminum-clad coating and materials have been verified to cause no side reactions within a -0.5 V to 5.0 V range, making these cases suitable for high-voltage (>4.5 V) battery research without interference.
  • Precision dimensional tolerance: All components are manufactured with ±0.02 mm dimensional tolerance, ensuring consistent assembly, elimination of gaps, and uniform pressure distribution across batches.

Trade-offs

  • Default accessories are 304 SS: The included spacers and springs are made of 304 stainless steel by default, which may not offer optimal corrosion resistance for highly aggressive or sulfide-containing electrolytes; customization is required for other materials.
  • Thin coating requires careful handling: The aluminum coating is only 5–10 μm thick; while it meets adhesion ≥5B grade, it may be susceptible to scratching or damage during assembly, requiring careful handling in the glovebox.
