ATOMFAIR CR2016 coin cell case sets are precision-machined stainless steel components for battery research. These components require strict dimensional tolerance control and material selection appropriate for the electrolyte corrosivity and operating voltage range.

  • Dimensional Tolerance: All components feature dimensions controlled within ±0.02 mm to ensure proper fit and prevent assembly gaps or uneven pressure.
  • Material Compatibility: The 316L/304 stainless steel cases and spacers must be selected based on the corrosivity and voltage range of the experimental system to avoid failure.
  • Batch Consistency: The precision tolerance ensures consistent performance across different batches and components.

What are the performance trade-offs between 316L and 304 stainless steel cases in CR2016 coin cell assemblies for high-voltage battery research?

The default accompanying accessories are 304 stainless steel; 316L offers superior corrosion resistance for aggressive electrolytes. Both materials are electrochemically verified to avoid side reactions within -0.5 V to 5.0 V, ensuring no interference with battery performance tests. For high-voltage or corrosive systems, 316L is recommended to mitigate pitting corrosion risk, while 304 is suitable for standard lithium-ion and sodium-ion chemistries.

Can the 15.8 × 0.5 mm spacers and 15.4 × 1.1 mm springs from the CR2016 set be used with thicker electrode stacks or alternative cathode/anode materials?

The spacers and springs are specifically dimensioned for CR2016 cell height (1.6 mm internal clearance). The spacer is 15.8 mm diameter × 0.5 mm thickness; the spring is 15.4 mm × 1.1 mm. For thicker electrode stacks, alternative spacer thicknesses may be required to maintain proper stack pressure. Customization is available by emailing inquiry@atomfair.com for non-standard dimensions.

What are the recommended storage and handling conditions for ATOMFAIR CR2016 coin cell case sets to ensure electrochemical cleanliness for glovebox assembly?

The cases are shipped with 100% dimensional inspection, sealing performance testing, and appearance inspection ensuring oil-free, burr-free, and impurity-free conditions. They can be used directly for battery assembly inside gloveboxes without additional cleaning. For extended storage, keep in original sealed packaging in a dry, inert atmosphere to prevent oxidation; avoid exposure to humidity to maintain surface passivation.

The Atomfair CR2016 coin cell case sets offer research-grade precision with ±0.02 mm tolerance control and verified electrochemical compatibility across -0.5 V to 5.0 V, making them suitable for standardized battery R&D. However, the default 304 stainless steel spacers and springs may limit use with highly corrosive electrolytes, and the fixed CR2016 form factor requires customization for other sizes.

Positive

  • High-precision dimensional tolerance: All component dimensions controlled within ±0.02 mm, ensuring consistent assembly, eliminating gaps and uneven pressure across batches for reproducible experimental data.
  • Rigorous electrochemical verification: Materials tested via constant potential polarization and cyclic voltammetry, confirming no side reactions within -0.5 V to 5.0 V range, preventing interference with battery performance measurements.

Trade-offs

  • Default 304 SS accessories limit corrosion resistance: Standard spacers and springs are 304 stainless steel, which may corrode in aggressive electrolyte chemistries; 316L or other materials require custom ordering.
  • Fixed CR2016 form factor constrains geometry: Sized only for CR2016 coin cells; spacer (15.8×0.5 mm) and spring (15.4×1.1 mm) dimensions are not adjustable for non-standard electrode stacks without customization.

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.
