Brand: ATOMFAIR®

This product consists of perforated 316L stainless steel coin cell case sets designed for gas-involved battery research. The material has been electrochemically verified to be stable within a -0.5 V to 5.0 V operating window; deviations may induce undesirable side reactions.

Electrochemical Voltage Window Constraint: The 316L stainless steel components have been tested to show no electrochemical side reactions within -0.5 V to 5.0 V; operation outside this range may compromise experimental integrity.

FAQ

What is the pore size range of the perforated positive case in the ATOMFAIR 316L CR2032 coin cell set, and how does the IP67 rating affect gas diffusion in lithium-air battery testing?

The perforated positive case has a pore size of 0.2–0.5 μm and is rated IP67 for waterproofing, which ensures uniform gas distribution while preventing electrolyte leakage, making it ideal for lithium-air and lithium-oxygen batteries. The precision-machined mesh design is specifically optimized for controlled gas permeation in gas-involved reaction systems.

Can the ATOMFAIR 316L CR2032 perforated coin cell case set be used with standard CR2032 battery test fixtures and gloveboxes?

Yes, the set is fully compatible with standard CR2032 fixtures and is designed for direct assembly inside gloveboxes. It includes all necessary components—perforated mesh positive case, 316L stainless steel negative case, 15.8 × 0.5 mm spacer, and 15.4 × 1.1 mm spring—and is shipped oil-free, burr-free, and impurity-free after 100% dimensional and sealing inspection.

What are the recommended operating conditions and handling requirements for the ATOMFAIR 316L CR2032 perforated coin cell case set in corrosive or high-voltage research environments?

The 316L stainless steel cases support an operating temperature range of –40°C to 150°C and a sealing pressure ≥6 MPa, making them suitable for sulfide solid-state batteries, high-voltage cells above 4.5 V, and long-term cycling in corrosive systems. The set is ready to use directly from packaging and requires no additional cleaning before glovebox assembly, as it is guaranteed oil-free and impurity-free.

Assessment

This 316L CR2032 perforated coin cell case set is designed for gas-involved battery research, featuring a precision mesh cap (0.2–0.5 μm, IP67) for controlled gas diffusion and corrosion-resistant 316L stainless steel construction. However, the default 304 stainless steel spacers and springs and exclusive CR2032 format limit its direct suitability for highly aggressive electrolytes or multi-format labs.

Positive

Precision Mesh for Controlled Gas Diffusion: The perforated positive cap features pores of 0.2–0.5 μm with an IP67 waterproof rating and uniform gas distribution design, enabling reliable and reproducible gas permeation experiments in lithium-air and lithium-oxygen battery research.
316L Stainless Steel Structural Integrity: The cases are fabricated from 316L stainless steel, offering enhanced corrosion resistance against sulfides, chlorides, and high-voltage electrolytes, with an operating temperature range up to 150°C and dimensional tolerance of ±0.02 mm for consistent assembly.

Trade-offs

Default 304 SS Spacers and Springs: The accompanying spacers (15.8 × 0.5 mm) and springs (15.4 × 1.1 mm) are made of 304 stainless steel as default, which may suffer corrosion in systems requiring the higher resistance of 316L, such as sulfide solid-state electrolytes or strong chloride environments.
Format-Specific Design (CR2032 Only): This set is configured exclusively for CR2032 coin cells; it is not directly compatible with CR2025 or CR2016 formats without custom component sourcing, limiting its use to one cell size in a standard lab setup.
