Gold-coated coin cell cases for electrochemical testing with specified contact resistance ≤1 mΩ and coating thickness 0.5–2 μm on 316L/304 stainless steel substrate. The cases are intended for wide electrochemical window testing and require clean, dry handling to maintain performance.

  • Coating Thickness: Gold coating thickness must be maintained within 0.5–2 μm to ensure consistent contact resistance.
  • Contact Resistance: Contact resistance is specified at ≤1 mΩ and requires clean, uncontaminated surfaces.
  • Substrate Material: The substrate is 316L/304 stainless steel, providing mechanical strength and corrosion resistance.
  • Intended Use: The cases are designed for ultra-precision electrochemical testing, EIS, micro-current measurements, and in-situ characterization.

How does the gold coating thickness affect contact resistance and electrochemical stability in ATOMFAIR Au-coated coin cell cases?

The gold coating thickness of 0.5–2 μm ensures a contact resistance of ≤1 mΩ while providing superior chemical stability across a -0.5 V to 5.0 V electrochemical window. Thicker coatings within this range enhance durability without compromising the low contact resistance specification, as all layers are rigorously tested via constant potential polarization and cyclic voltammetry to guarantee no side reactions.

Are ATOMFAIR Au-coated coin cell cases compatible with high-voltage cathode materials like NMC or LCO?

Yes, the gold coating on 316L/304 stainless steel substrates provides a stable electrochemical window from -0.5 V to 5.0 V, verified by constant potential polarization and cyclic voltammetry, ensuring no side reactions with high-voltage cathodes. This makes them directly suitable for NMC, LCO, and other high-voltage materials without interfering with battery performance test results.

What handling precautions are necessary for ATOMFAIR Au-coated coin cell cases to maintain their low contact resistance?

These cases are shipped oil-free, burr-free, and impurity-free after 100% dimensional inspection, coating thickness verification, and sealing performance testing, allowing direct use inside gloveboxes without additional cleaning. To preserve the ≤1 mΩ contact resistance, avoid touching the gold-coated surfaces with bare hands and store in a dry, inert atmosphere to prevent oxidation or contamination.

These Au-coated coin cell cases deliver ≤1 mΩ contact resistance and verified electrochemical stability within -0.5 V to 5.0 V, making them well-suited for EIS and micro-current measurements. However, the included spacers and springs are 304 stainless steel (not gold-coated), and the sets are pre-configured for CR2032 format only, requiring custom orders for other sizes or materials.

Positive

  • High-Precision Dimensional Tolerance: All component dimensions are controlled within ±0.02 mm, ensuring perfect inter-batch matching and eliminating assembly gaps or uneven pressure caused by dimensional errors.
  • Validated Electrochemical Window: Materials have passed constant potential polarization and cyclic voltammetry tests, confirming no side reactions within -0.5 V to 5.0 V, guaranteeing no interference with battery performance results.

Trade-offs

  • Uncoated Steel Accessories: The included spacers and springs are made of 304 stainless steel rather than gold-coated material, which may limit corrosion resistance in highly aggressive or wide-window electrolyte systems.
  • Fixed CR2032 Format Only: The case sets are supplied exclusively in CR2032 configuration; obtaining other sizes, models, or materials requires a separate customization request, adding lead time and minimum order considerations.

Every advanced material, component, equipment, and instrument in our catalog is backed by rigorous testing. We maintain strict internal quality management frameworks and align with CE conformity metrics to deliver transparent, reproducible performance data via our public open-science repository.
