Description

ATOMFAIR PURE ALUMINUM SPACER Φ15.5×0.4MM 99.5% AL 60PCS/PACK

RESEARCH GRADE MATERIAL

Product Overview
ATOMFAIR® Pure Aluminum Spacer (Φ15.5mm × 0.4mm) is manufactured from high-purity aluminum material with Al purity > 99.5%, specifically designed for 20-series specialty coin cell battery assembly. This spacer provides excellent electrical conductivity and stable contact pressure between electrode components, ensuring reliable internal conductive pathways and consistent electrochemical performance. The strict control of impurity elements—including Si, Fe, Cu, Mn, Mg, Pb, Zn, and Ti—minimizes parasitic side reactions and metal contamination within the cell, making it ideal for research-grade lithium battery testing where impurity interference must be eliminated. Each pack contains 60 pcs of spacers, conveniently packaged for laboratory use.

Key Features & Advantages
  • High-Purity Aluminum (>99.5%) for Superior Conductivity: Premium-grade aluminum substrate delivers excellent electrical conductivity, ensuring stable current collection and minimal contact resistance within coin cell assemblies.
  • Strict Impurity Control for Research-Grade Applications: Rigorous limits on Si, Fe, Cu, Mn, Mg, Pb, Zn, and Ti impurities—each element strictly controlled to ppm-level thresholds—minimizes parasitic reactions and metal contamination that could compromise electrochemical data integrity.
  • Precision Φ15.5mm × 0.4mm Dimensions: Optimized for 20-series specialty coin cells, providing consistent contact pressure and spacing between electrode components without short-circuit risk or excessive compression.
  • Convenient 60-Piece Laboratory Packaging: Each pack contains 60 individually cut spacers, providing ample supply for multiple coin cell assembly batches while maintaining contamination-free storage.

APPLICATION SCOPE: Specifically designed for 20-series specialty coin cell batteries, including CR2032, LIR2032, and other Φ20mm coin cell formats. Suitable for lithium-ion battery research, lithium metal half-cell assembly, and electrochemical testing where high-purity aluminum current collectors are required. Compatible with both conventional coin cell crimping equipment and glovebox assembly workflows.
PACKAGING: Each pack contains 60 pcs of Φ15.5mm × 0.4mm pure aluminum spacers. Individually cut and packaged to maintain surface cleanliness and prevent oxidation contamination during storage. All spacers are manufactured from high-purity aluminum (>99.5%) with strict impurity control.
IMPORTANT NOTICE: This spacer is designed for use with 20-series specialty coin cells. Ensure proper alignment during assembly to avoid short circuits or uneven pressure distribution. Handle with clean tweezers to prevent surface contamination—surface oils or particles may increase contact resistance. Replace spacers between experiments to avoid cross-contamination.

This spacer must be used within standard electrochemical operating windows to prevent side reactions. It is specifically dimensioned for CR20 series coin cell assemblies with a tolerance of ±0.02 mm.

  • Compatibility Constraint: The spacer is compatible only with CR20 series coin cell assemblies; deviation may cause poor contact.
  • Handling Precision: The ±0.02 mm dimensional tolerance must be preserved during handling to ensure consistent performance.
  • Operating Window: Electrochemical stability is maintained only within standard operating windows; exceeding these may induce side reactions.

How does the ±0.02 mm dimensional tolerance of ATOMFAIR pure aluminum spacers affect contact pressure uniformity and experimental reproducibility in coin cell assembly?

The ±0.02 mm tolerance ensures uniform contact pressure across the electrode stack by eliminating assembly gaps and uneven loading between batches. This strict dimensional control directly reduces systematic errors in electrochemical testing, as verified by 100% dimensional inspection before shipment.

Are ATOMFAIR pure aluminum spacers electrochemically compatible with sodium-ion battery electrolytes and high-voltage cathode materials?

Yes, these spacers are specifically optimized for conventional Li-ion and Na-ion battery research. They have been verified by constant potential polarization and cyclic voltammetry to exhibit no electrochemical side reactions within the -0.5 V to 5.0 V window, making them suitable for protecting high-voltage current collectors in demanding electrolytes.

Can ATOMFAIR pure aluminum spacers be used directly in an argon-filled glovebox without additional cleaning or surface treatment?

Yes, the spacers are shipped oil-free, burr-free, and impurity-free after 100% dimensional and surface quality inspection. They are designed for direct use in battery assembly inside gloveboxes, eliminating the need for pre-cleaning or surface preparation.

These pure aluminum spacers (99.5%) provide precise dimensional tolerance (±0.02 mm) and verified electrochemical stability from -0.5 V to 5.0 V, making them suitable for standard coin cell testing; however, the 0.5 mm thickness demands careful handling to avoid deformation, and performance beyond the tested voltage window may introduce side reactions.

Positive

  • High-precision dimensional tolerance: All spacers are held to ±0.02 mm tolerance, ensuring consistent mechanical contact and eliminating assembly gaps across batches.
  • Verified electrochemical compatibility: Constant potential and cyclic voltammetry tests confirm no side reactions within -0.5 V to 5.0 V, preventing interference in Li-ion/Na-ion cell performance.

Trade-offs

  • Thin geometry requires careful handling: The 0.5 mm thickness and pure aluminum construction make the spacers susceptible to bending or deformation if not handled with proper tweezers or during automated assembly.
  • Limited voltage window for absolute stability: Electrochemical stability is only verified between -0.5 V and 5.0 V; outside this range (e.g., high-voltage cathodes >5 V) aluminum may corrode or participate in side reactions.
