This spacer requires clean handling to prevent surface contamination that increases contact resistance. Use only with 20-series coin cells and replace between experiments to avoid cross-contamination.
- Contamination Control: Handle the spacer only with clean tweezers to avoid transferring oils or particles that elevate contact resistance.
- Alignment Requirement: Ensure the spacer is centered on the electrode stack to prevent short circuits or uneven pressure distribution during crimping.
- Replacement Protocol: Discard the spacer after each experiment and use a fresh one to eliminate cross-contamination between cells.
- Compatibility: This spacer is designed exclusively for 20-series specialty coin cells such as CR2032 and LIR2032.
- Storage: Store spacers in their original packaging to maintain surface cleanliness and prevent oxidation prior to use.
Follow these steps to incorporate the spacer into a 20-series coin cell battery. Proper handling and alignment ensure reliable electrical contact and data quality.
Required Equipment: Clean tweezers, Coin cell crimping machine
- Transfer Spacer
Use clean tweezers to transfer the spacer from its packaging to the coin cell assembly area. - Align Spacer
Position the spacer centrally on the electrode stack inside the coin cell casing. - Crimp Assembly
Crimp the coin cell using standard equipment, ensuring even pressure distribution across the spacer. - Discard After Use
After completing the experiment, discard the used spacer and do not reuse it for subsequent cells.
How does the impurity level of aluminum spacers affect coin cell electrochemical performance?
The Atomfair Pure Aluminum Spacer uses high-purity aluminum (>99.5%) with strict control of impurities including Si (<0.035%), Fe (<0.198%), Cu (<0.013%), Mn (<0.0083%), Mg (<0.002%), Pb (<0.013%), Zn (<0.016%), and Ti (<0.012%). These ppm-level limits minimize parasitic side reactions and metal contamination that could compromise electrochemical data integrity, making it suitable for research-grade lithium battery testing where impurity interference must be eliminated.
Can this Φ15.5 mm aluminum spacer be used in standard CR2032 coin cells or only specialty 20-series cells?
Yes, this spacer is specifically designed for 20-series specialty coin cell batteries including CR2032, LIR2032, and other Φ20 mm coin cell formats. It is compatible with lithium-ion battery research, lithium metal half-cell assembly, and electrochemical testing requiring high-purity aluminum current collectors. Proper alignment during assembly is critical to avoid short circuits or uneven pressure distribution.
What are the critical handling and storage requirements for aluminum spacers to maintain electrochemical integrity in coin cell assembly?
Handle spacers with clean tweezers to prevent surface contamination from oils or particles that increase contact resistance. Replace spacers between experiments to avoid cross-contamination. The spacers are individually cut and packaged to maintain surface cleanliness and prevent oxidation contamination during storage. They are compatible with glovebox assembly workflows, and proper alignment in 20-series specialty coin cells is required to avoid short circuits or uneven pressure.
The Atomfair Pure Aluminum Spacer (Φ15.5×0.4mm, 99.5% Al) delivers research-grade purity and strict impurity control for 20-series coin cells, but requires careful handling to avoid surface contamination and must be properly aligned to prevent short circuits.
Positive
- High-purity aluminum with strict impurity control: Al purity >99.5% with ppm-level limits on Si, Fe, Cu, Mn, Mg, Pb, Zn, Ti minimizes parasitic side reactions and metal contamination in research-grade battery testing.
- Precision dimensions for consistent contact: Φ15.5mm × 0.4mm dimensions ensure stable contact pressure and reliable electrical conductivity in 20-series specialty coin cells without risk of short-circuit or excessive compression.
Trade-offs
- Requires contamination-free handling: Surface oils, particles, or fingerprints from unclean tools can increase contact resistance; spacers must be handled with clean tweezers and replaced between experiments to avoid cross-contamination.
- Specific to 20-series coin cell formats: Designed exclusively for 20-series specialty coin cells (e.g., CR2032, LIR2032); improper alignment or use with non-compatible cells may cause uneven pressure or short circuits.
