This coin cell case set is designed for battery research under strict dimensional and electrochemical compatibility constraints. All components must be used within specified temperature and sealing pressure ranges and assembled in an inert atmosphere to prevent contamination.
- Electrochemical Compatibility: The case materials are verified to exhibit no side reactions within a -0.5 V to 5.0 V potential window.
- Dimensional Tolerance: All component dimensions are controlled to within ±0.02 mm to ensure uniform assembly pressure and prevent leakage.
- Operating Temperature Range: The 304 stainless steel case is rated for -40°C to 120°C, while the 316L variant is rated for -40°C to 150°C.
- Sealing Pressure Requirement: A sealing pressure of at least 5 MPa for 304 steel or 6 MPa for 316L steel must be applied during crimping.
- Atmosphere Requirement: Components are ready for direct use in an argon-filled glovebox without further cleaning.
Assemble the coin cell inside a glovebox to maintain an inert atmosphere. Follow these steps to ensure proper sealing and electrochemical performance.
Required Equipment: Argon-filled glovebox, Crimping press
- Inspect components
Verify that the coin cell case, spacer, and spring are free of oil, burrs, and impurities before assembly. - Transfer to glovebox
Transfer the components into an argon-filled glovebox to maintain an inert atmosphere. - Assemble electrode stack
Assemble the electrode stack, spacer, and spring inside the coin cell case. - Crimp the cell
Crimp the assembled coin cell using a crimping press at a sealing pressure of at least 5 MPa for 304 steel or 6 MPa for 316L steel.
What are the performance trade-offs between using 304 stainless steel versus 316L stainless steel for the CR2025 coin cell case in high-voltage or corrosive battery systems?
The 316L stainless steel variant offers a higher sealing pressure of ≥6 MPa (vs. ≥5 MPa for 304), a wider operating temperature range of -40°C to 150°C (vs. -40°C to 120°C), and superior resistance to sulfide and chloride ion corrosion, making it optimal for sulfide solid-state batteries, high-voltage systems exceeding 4.5 V, and long-term cycling tests. The 304 stainless steel variant is suited for conventional lithium-ion, sodium-ion, and aqueous battery testing where corrosive conditions are not extreme.
Can the ATOMFAIR CR2025 coin cell case be used for sulfide solid-state batteries or high-voltage systems?
Yes, but only the 316L stainless steel variant is explicitly recommended for sulfide solid-state batteries and high-voltage batteries (>4.5 V) due to its sulfide/chloride ion corrosion resistance and higher sealing pressure of ≥6 MPa. The 304 stainless steel variant is not rated for these aggressive conditions. Both variants are compatible with conventional lithium-ion, sodium-ion, all-solid-state, and lithium-air research systems within the specified voltage range of -0.5 V to 5.0 V.
Are the ATOMFAIR CR2025 coin cell cases ready for direct use in an argon glovebox without additional cleaning?
Yes, every case set undergoes 100% dimensional inspection, sealing performance testing, and appearance inspection before shipment, ensuring an oil-free, burr-free, and impurity-free condition. They can be used directly for battery assembly inside gloveboxes without any additional cleaning or preparation. Standard packaging is 1000 sets per pack.
The ATOMFAIR CR2025 coin cell case set offers a choice of 304 or 316L stainless steel cases with ±0.02 mm dimensional tolerance, but default accessories (spacers, springs) are 304 SS, requiring custom ordering for full 316L compatibility. Material selection directly affects sealing pressure and temperature limits: 304 supports ≤120°C/≥5 MPa, while 316L supports ≤150°C/≥6 MPa, making the latter necessary for high-voltage (>4.5 V) or corrosive electrolyte systems.
Positive
- Precision dimensional control: All component dimensions are held within ±0.02 mm tolerance, ensuring consistent assembly and seal integrity across batches.
- 316L variant enhanced durability: The 316L stainless steel case offers a sealing pressure of ≥6 MPa and an operating temperature range of -40°C to 150°C, making it suitable for high-voltage (>4.5 V) and corrosive electrolyte systems.
Trade-offs
- Default accessory material limitation: The standard kit includes 304 stainless steel spacers and springs; 316L or other material accessories require custom ordering via email.
- 304 variant temperature and pressure limits: The 304 stainless steel case is rated for sealing pressure ≥5 MPa and operating temperature up to 120°C, which may constrain use in high-temperature or high-pressure research systems.
