FAQ

How does the 0.2–0.5 μm pore size of the mesh positive cap balance gas diffusion with electrolyte leakage prevention in lithium-air coin cells?

The mesh pore size of 0.2–0.5 μm is designed to allow uniform oxygen diffusion while maintaining an IP67 waterproof rating, preventing electrolyte leakage. This precision range ensures consistent gas distribution for lithium-air reactions without compromising sealing integrity. The 316L stainless steel construction provides additional corrosion resistance against reactive oxygen species.

Can the ATOMFAIR CR2032 316L lithium-air coin cell case set be used with sulfide-based solid-state electrolytes or high-voltage cathode materials above 4.5 V?

Yes, the 316L stainless steel case material is rated for sealing pressure ≥6 MPa and operating temperature up to 150°C, with electrochemical stability verified from -0.5 V to 5.0 V. This makes it suitable for high-voltage systems (>4.5 V) and corrosive environments including sulfide solid-state electrolytes. However, the default spacers and springs are 304 stainless steel; for highly corrosive systems, 316L or coated spacers should be specified via customization.

What pretreatment is required before using the ATOMFAIR lithium-air coin cell case sets in an argon-filled glovebox?

No pretreatment is required. Each set is shipped 100% dimensionally inspected, with pore size verification, sealing performance testing, and appearance inspection to ensure oil-free, burr-free, and impurity-free conditions. The components are ready for direct battery assembly inside gloveboxes without additional cleaning or modification.

Assessment

This specialized 316L stainless steel coin cell case set features a precision-machined mesh positive cap (0.2–0.5 μm pores, IP67-rated) optimized for lithium-air and gas-involved battery research. High dimensional tolerance (±0.02 mm) ensures consistent assembly, but included spacers and springs default to 304 stainless steel, requiring customization for full corrosion resistance in highly aggressive systems.

Positive

Precision-machined mesh cap for gas diffusion: The positive cap integrates a 0.2–0.5 μm pore mesh with IP67 waterproof rating, enabling uniform gas distribution critical for lithium-air and lithium-oxygen cells while preventing electrolyte leakage.
±0.02 mm dimensional tolerance across components: All components (case, spacers, springs) are manufactured to ±0.02 mm tolerance, ensuring gap-free assembly and consistent electrode pressure across batches, reducing experimental systematic errors.

Trade-offs

Default spacers and springs are 304 stainless steel: While the case is 316L stainless steel, the accompanying spacers (Φ15.8 × 0.5 mm) and springs (Φ15.4 × 1.1 mm) are 304 stainless steel by default, which may corrode in sulfide- or chloride-containing electrolytes unless customized to 316L.
Customization requires email order for non-standard configurations: Alternative sizes, model variants, or materials beyond the offered CR2032 316L/304 configuration require custom email requests, limiting off-the-shelf flexibility for researchers needing immediate variation in dimensions or coatings.
