FAQ

What are the performance trade-offs between 304 stainless steel and 316L stainless steel for CR2016 coin cell cases in battery research?

The primary trade-off is between cost and corrosion/thermal performance. The 304SS cases offer sealing pressure ≥5 MPa and operating temperature range -40°C to 120°C, suitable for conventional Li-ion and Na-ion batteries. The 316L cases provide higher sealing pressure ≥6 MPa, extended operating temperature up to 150°C, and superior resistance to sulfide and chloride ion corrosion, making them preferred for sulfide solid-state batteries, high-voltage systems (>4.5 V), and long-term cycling tests in highly corrosive environments.

Can the ATOMFAIR CR2016 coin cell case set be used for sulfide solid-state battery research?

Yes, but only with the 316L stainless steel variant. The product description specifies the 316L material for sulfide solid-state batteries due to its sulfide/chloride ion corrosion resistance and higher operating temperature (up to 150°C). The 304SS variant is recommended for conventional lithium-ion and sodium-ion systems and is not explicitly validated for sulfide-containing electrolytes. All variants are electrochemically verified within -0.5 V to 5.0 V to avoid side reactions.

What infrastructure is required for handling and assembling ATOMFAIR CR2016 coin cell cases in a laboratory setting?

The cases are shipped oil-free, burr-free, and impurity-free, enabling direct assembly inside an inert-atmosphere glovebox without pre-cleaning. Each set includes cases, spacers (Φ15.8 × 0.5 mm), and springs (Φ15.4 × 1.1 mm), all with dimensional tolerance ±0.02 mm to ensure consistent sealing. Standard packaging is 1000 sets/pack, and no special storage beyond a dry, contaminant-free environment is required based on the stated operating temperature range of -40°C to 120°C (304SS) or -40°C to 150°C (316L).

Assessment

This CR2016 coin cell case set offers 304 and 316L stainless steel variants with ±0.02 mm dimensional tolerance and verified electrochemical inertness from -0.5 V to 5.0 V. Material selection is critical for corrosive systems, and the included wave spring's 5–30 N clamping force may limit electrode thickness versatility.

Positive

High-precision dimensional tolerance control: All components are machined to ±0.02 mm tolerance, ensuring consistent assembly and eliminating uneven pressure distribution across batches.
Electrochemically verified material compatibility: Cases and accessories have been tested via constant potential polarization and cyclic voltammetry to confirm no side reactions within -0.5 V to 5.0 V, preserving test accuracy.

Trade-offs

Material selection critical for corrosive systems: Default 304 stainless steel may suffer corrosion in sulfide solid-state, high-voltage (>4.5 V), or highly acidic/alkaline electrolytes; 316L or coated variants must be sourced via custom order.
Fixed spring force range limits electrode thickness versatility: The included wave spring provides 5–30 N clamping force, which may not be optimal for very thin or very thick electrodes; alternative spring types require custom request.
