The aluminum-clad coating has adhesion grade ≥5B and thickness of 5–10 μm, requiring careful handling to avoid scratching or delamination. The spring must be used within its force range of 5–30 N and with CR2032 compatible cells to ensure proper contact and fatigue life.

  • Coating Integrity: Inspect the spring visually for coating defects before assembly and avoid abrasive contact with the coated surface.

What performance trade-offs exist between the aluminum-clad coating and the underlying stainless steel for wave springs used in high-voltage coin cell testing?

The aluminum-clad coating (5–10 μm, adhesion ≥5B grade) provides electrochemical stability, having been verified to cause no side reactions within a -0.5 V to 5.0 V voltage range, while the stainless steel core delivers mechanical strength and a fatigue life ≥10,000 cycles. This combination balances corrosion resistance and contact conductivity against the spring's structural load capacity, making it suitable for thin electrode and low-loading battery applications without compromising cell internal pressure stability.

Can ATOMFAIR Al-Clad Wave Springs be integrated into cell formats other than CR2032, such as CR2016 or custom pouch cells?

The default 15.4 × 1.1 mm dimensions are specifically designed to fit CR2032 and all CR20 series internal dimensions. For other cell formats including CR2016 (different height) or pouch cells, customizable sizing variants are available upon request via inquiry@atomfair.com, allowing adaptation to unique geometry and pressure requirements.

Is any pre-cleaning or surface preparation required before using these wave springs in an argon glovebox for battery assembly?

No pre-cleaning is necessary. Each spring is shipped after 100% dimensional inspection, coating thickness verification, spring force calibration, and appearance inspection, ensuring oil-free, burr-free, and impurity-free conditions. They are ready for direct use inside gloveboxes without additional surface treatment.

The ATOMFAIR Al-Clad Wave Springs deliver a spring force range of 5–30 N with fatigue life ≥10,000 cycles, engineered for stable cell internal pressure in routine testing, thin electrode, and low-loading battery applications. They are dimensioned for CR2032/CR20 cells and verified for electrochemical compatibility within -0.5 V to 5.0 V, but the fixed force range and cell format restriction limit broader utility without customization.

Positive

  • High-Precision Dimensional Tolerance: All component dimensions are controlled within ±0.02 mm, ensuring consistent matching across batches and eliminating assembly gaps and uneven pressure issues.
  • Electrochemical Compatibility Verified: Materials have undergone constant potential polarization and cyclic voltammetry tests confirming no side reactions within a -0.5 V to 5.0 V voltage range, guaranteeing no interference with battery performance results.

Trade-offs

  • Limited Spring Force Range: The spring force is fixed between 5 N and 30 N; applications requiring higher or lower clamping pressures are not supported without custom ordering.
  • Default Size Restricted to CR20 Cells: The default 15.4 × 1.1 mm dimensions are optimized for CR2032 and CR20 series internal diameters; use in other cell formats requires a custom order.
