Key Features & Advantages
  • Homogeneous Material Purity: Features an uncompromised structural configuration with highly uniform elemental distribution across the 0.45mm matrix.
  • Enhanced Mechanical Stability: Increased 0.45mm cross-section delivers superior handling characteristics compared to traditional ultra-thin foils.
  • Optimized Sintering/Microstructure: Advanced synthesis allows for lower required operating temperatures and ideal grain boundary integration during cell fabrication.

APPLICATION SCOPE: Secondary Sodium-Ion Battery Prototyping, Thick-electrode Configuration, and Electrochemical Interface Analytics.
PACKAGING: 100 pcs per rigid sealed inner micro-storage container wrapped in industrial vacuum foil.
IMPORTANT NOTICE: This product is highly sensitive to ambient exposure. The outmost jar contains air; keep it sealed and transfer directly into an anhydrous inert gas glovebox environment before opening. The inner aluminum foil bag is vacuum-packed under an Argon environment. NEVER open the foil bag in air to prevent catastrophic oxidation. If the bag leaks upon arrival, take photos immediately for post-sale replacement prior to unsealing. Sodium rings without current collectors are structurally fragile. It is highly recommended to heat the matrix substrate above 50°C using a heating pad or thermal chamber inside the glovebox before peeling to simplify membrane removal. Always tighten the inner micro-bottle cap immediately inside the glovebox when not in use to avoid parasitic degradation.

Frequently Asked Technical Questions

Why is the 0.45mm sodium ring preferred as a battery current collector material？

ATOMFAIR® 0.45mm Sodium Ring functions as a premier battery current collector material for advanced systems. It delivers optimal matrix uniformity and high thick-film energy density parameters, significantly boosting performance metrics and phase purity during laboratory testing workflows.

How to handle fragile sodium rings？

To successfully solve how to handle fragile sodium rings without secondary contamination, this material must be handled strictly according to substrate pre-heating on a heating pad above 50°C before peeling to simplify membrane removal.

How does ATOMFAIR® 0.45mm Sodium Ring compare to traditional alternative options regarding operational stability?

Compared to standard alternatives, the optimized matrix of ATOMFAIR® 0.45mm Sodium Ring incorporates specialized chemical doping. This unique architecture dramatically enhances structural resistance against degradation, preserving long-term validation integrity.

What material processing benefits does the microstructure of ATOMFAIR® 0.45mm Sodium Ring offer?

Boasting engineered particle structuring and optimized specific surface area, this product offers superior sinterability. The controlled form factor facilitates lower thermal processing thresholds and promotes ideal grain boundary integration during cell fabrication.

How is the phase purity and quality control of this research-grade batch validated?

Every competitive batch undergoes rigid analytical quality validation testing. Total elemental and metallic impurities are strictly regulated below strict industry thresholds to eliminate parasitic electronic leakage and maintain uncompromised data reproducibility.

This high-purity sodium metal ring is highly reactive with moisture and oxygen, requiring storage and handling in an inert atmosphere to prevent oxidation and degradation. The material's ductility and softness necessitate careful mechanical handling to avoid deformation or tearing during cell assembly.

  • Environmental Storage Constraint: Store the sodium ring foil in an argon-filled glovebox with oxygen and moisture levels below 0.1 ppm to maintain chemical integrity.
  • Mechanical Handling Constraint: Use non-marring, PTFE-coated tweezers to handle the foil, as metal tools can cause surface contamination or physical damage.
  • Assembly Compatibility Constraint: Ensure the current collector variant (aluminum or copper) is compatible with the intended electrolyte system to avoid galvanic corrosion.
  • Safety Constraint: Never expose the sodium metal to water or alcohols, as violent exothermic reactions will occur.

This procedure outlines the safe handling and integration of the reactive sodium ring foil as an anode in a standard coin cell. Strict adherence to inert atmosphere conditions is required throughout all steps.

Required Equipment: Argon-filled glovebox (O2 and H2O < 0.1 ppm), PTFE-coated tweezers, Coin cell crimping machine

  1. Prepare Glovebox Environment
    Verify that the glovebox atmosphere is inert with oxygen and moisture levels below 0.1 ppm before introducing any materials.
  2. Retrieve Sodium Ring Foil
    Transfer the sealed sodium ring foil package into the glovebox antechamber and purge it three times with argon before opening.
  3. Inspect Foil Integrity
    Visually inspect the sodium ring for any discoloration, pitting, or mechanical damage using PTFE-coated tweezers to handle it.
  4. Position on Current Collector
    Center the sodium ring foil onto the pre-cut current collector disk (aluminum or copper) ensuring full contact without air gaps.
  5. Assemble Coin Cell Stack
    Place the sodium ring/collector assembly into the coin cell case bottom, followed by the separator, electrolyte, and cathode stack in sequence.
  6. Crimp Coin Cell
    Transfer the assembled cell stack to the crimping machine and apply the manufacturer-specified pressure to seal the coin cell hermetically.
  7. Remove Cell from Glovebox
    Transfer the sealed coin cell out of the glovebox only after confirming the crimp is complete and no sodium is exposed.

How does the 0.45 mm thickness of the ATOMFAIR sodium ring foil affect electrochemical performance compared to thinner sodium foils?

The 0.45 mm thickness provides superior mechanical stability and handling compared to standard thin disks (≤0.2 mm) that are highly ductile and deform easily. However, this increased cross-section introduces a performance trade-off: while it reduces the risk of short circuits from foil deformation during cell assembly, the thicker foil may lead to higher internal resistance and lower sodium utilization efficiency, which must be accounted for in capacity modeling. The high-purity sodium metal matrix ensures homogeneous elemental distribution across the 0.45 mm profile.

Which current collector variant is recommended for standard sodium-ion coin cell assembly with the ATOMFAIR sodium ring foil?

The Aluminum Foil Current Collector variant is the most widely selected industry configuration for seamless cell integration, as stated in the product specifications. Available variants include aluminum, copper, or no current collector, allowing researchers to tailor the configuration to specific anode or cathode requirements. For standard half-cell testing, aluminum is preferred to avoid alloying reactions with sodium metal.

What storage and handling conditions are required for the ATOMFAIR sodium ring foil to maintain its integrity before use?

The sodium ring foils are packaged in a sealed inner vacuum pack under an argon (Ar) gas environment to prevent oxidation and moisture contamination. They should be stored in an inert-atmosphere glovebox and handled with care to avoid exposure to air and humidity, as sodium metal is highly reactive. The product is processed under strict SJ/T11363-2006 compliance conditions and supplied in a standard packaging of 100 pieces per box.

This 0.45mm sodium ring foil with current collector offers enhanced mechanical stability over standard thin disks, but requires strict inert atmosphere handling and careful selection of current collector variant for optimal cell integration.

Positive

  • Enhanced mechanical stability: The 0.45mm thickness provides superior handling characteristics and reduced deformation compared to standard thin disks (≤0.2mm), improving cell assembly consistency.
  • Homogeneous material purity: High-purity sodium metal with uniform elemental distribution across the matrix ensures reliable baseline testing and minimizes operational variables in electrolyte validation.

Trade-offs

  • Strict inert atmosphere required: The product is sealed in an argon gas environment vacuum pack; exposure to ambient air or moisture will rapidly degrade the sodium metal, necessitating glovebox handling for all operations.
  • Current collector variant dependency: While the aluminum foil current collector variant is the most widely selected for seamless integration, other variants may require additional compatibility testing with specific cell architectures.
