Ti-coated CR2032 cases resist strong acid/base corrosion and maintain electrochemical stability within -0.5 V to 5.0 V. Assembly requires oil-free, burr-free, and impurity-free components, suitable for direct use in a glovebox.
- Chemical Compatibility: The titanium coating and stainless steel substrate tolerate strongly acidic and alkaline electrolytes.
- Voltage Tolerance: Electrochemical testing confirms no side reactions within a -0.5 V to 5.0 V potential window.
- Dimensional Precision: All component dimensions are controlled to ±0.02 mm to ensure consistent assembly pressure and sealing.
- Cleanliness Requirement: Each set is verified oil-free, burr-free, and impurity-free prior to shipment.
- Assembly Environment: Cases are ready for direct battery assembly inside an inert-atmosphere glovebox.
What electrochemical voltage window is the titanium coating on these CR2032 cases verified for, and does it limit the usable voltage range for high-voltage battery testing?
The titanium-coated cases have been rigorously verified via constant potential polarization and cyclic voltammetry to have no side reactions within a -0.5 V to 5.0 V range, making them suitable for high-voltage testing up to 5.0 V without interfering with battery performance results.
Are the included 304 stainless steel spacers and springs suitable for use with strongly acidic or alkaline electrolytes in a bio-battery application?
The default spacers and springs are made of 304 stainless steel, which provides general corrosion resistance but may not be optimal for strongly acidic or alkaline electrolytes; the titanium coating only applies to the cases. For such aggressive electrolyte systems, Atomfair recommends contacting their engineering team for customized accessory materials.
Can these titanium-coated coin cell case sets be used directly in an argon glovebox without additional cleaning or degreasing?
Yes, each set undergoes 100% dimensional inspection, coating thickness verification, sealing performance testing, and appearance inspection before shipment, ensuring they are oil-free, burr-free, and impurity-free, allowing direct use for battery assembly inside gloveboxes.
The ATOMFAIR Ti-Coated CR2032 coin cell cases provide excellent corrosion resistance and biocompatibility for aggressive electrolyte systems, but the included 304 SS spacers and springs may require upgrading for full chemical compatibility, and the 3-8 μm coating range introduces thickness variability that could affect electrochemical reproducibility.
Positive
- Corrosion-resistant titanium coating for aggressive electrolytes: The 3-8 μm titanium coating on a stainless steel substrate provides excellent biocompatibility and resistance to strong acids/bases, enabling reliable use in bio-batteries, aqueous zinc batteries, and corrosive systems.
- High-precision dimensional tolerance for assembly consistency: All components are manufactured with tolerance control within ±0.02 mm, ensuring perfect matching across batches and eliminating assembly gaps or uneven pressure.
Trade-offs
- Included accessories lack corrosion resistance: The default spacers (15.8×0.5 mm) and springs (15.4×1.1 mm) are made of 304 stainless steel, which may corrode or leach ions in the strongly acidic/alkaline or bio-battery environments the cases are designed for; customization to compatible materials is recommended.
- Coating thickness specified as a range: The titanium coating thickness is given as 3–8 μm, meaning individual sets may vary, potentially affecting contact resistance or electrochemical performance reproducibility across experiments.
