These coin cell case sets require precise dimensional matching and material selection based on electrolyte corrosivity and operating voltage. Assembly must ensure uniform contact to prevent gaps and uneven pressure that cause leakage or performance degradation.

  • Dimensional Tolerance: All components have dimensions controlled within ±0.02 mm to ensure batch-to-batch uniformity and proper sealing.
  • Material Selection: Choose 316L stainless steel for highly corrosive electrolytes and 304 stainless steel for standard conditions to avoid corrosion-induced failure.
  • Component Compatibility: The 15.8 x 0.5 mm spacers and 15.4 x 1.1 mm springs are designed to fit CR2025 cases precisely; substitution may cause assembly issues.

How does the ±0.02 mm dimensional tolerance of these coin cell cases affect reproducibility in long-duration cycling tests?

The strict ±0.02 mm tolerance control ensures uniform pressure distribution and eliminates assembly gaps, directly reducing systematic errors across batches. This results in highly consistent cell performance, which is critical for obtaining reliable and reproducible cycling data in research.

Are these CR2025 case sets compatible with high-voltage cathode materials operating above 4.5 V?

Yes, the stainless steel components have been electrochemically verified via constant potential polarization and cyclic voltammetry to exhibit no side reactions within the -0.5 V to 5.0 V range, making them fully compatible with high-voltage materials up to 5.0 V.

Do these coin cell case sets require any pre-cleaning or surface treatment before assembly in an inert atmosphere glovebox?

No pre-cleaning is necessary. The cases are shipped oil-free, burr-free, and impurity-free after undergoing 100% dimensional and sealing inspection, allowing direct use in glovebox environments for battery assembly.

The ATOMFAIR CR2025 coin cell case set provides 316L/304 stainless steel cases, spacers, and springs with ±0.02 mm tolerance and electrochemical compatibility verified for -0.5V to 5.0V, suitable for academic battery research. However, default accessories are 304 stainless steel and the minimum pack size is 1000 sets, requiring customization for alternative materials.

Positive

  • High-Precision Tolerance Control: ±0.02 mm: All component dimensions are strictly controlled within ±0.02 mm, ensuring perfect matching between batches and eliminating assembly gaps or uneven pressure during cell assembly.
  • Electrochemical Compatibility Tested: -0.5 to 5.0V: Materials have undergone constant potential polarization and cyclic voltammetry tests, confirming no side reactions within a -0.5V to 5.0V range, preventing interference with battery performance data.

Trade-offs

  • Default Accessories Are 304 Stainless Steel: Default accompanying accessories are made of 304 stainless steel. Researchers requiring 316L or other materials must request customization via email, which may add lead time to procurement.
  • Large Minimum Pack Quantity: 1000 Sets: Standard packaging is 1000 sets per pack. Smaller labs or pilot studies may find this quantity excessive, increasing upfront inventory commitment and storage requirements.

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.
