What is the coating purity and thickness of the aluminum coating on the LIR2025 coin cell case?
The coating is pure aluminum with 99.9% purity and approximately 1 µm thickness, applied to the positive case surface of the 304 stainless steel case.
What are the dimensional tolerances for the lower case and positive case of the LIR2025 coin cell case?
The lower case has outer diameter approximately 19.95 mm, inner diameter approximately 19.90 mm, and height 2.30 +/- 0.04 mm. The positive case has inner diameter 16.5 +/- 0.05 mm, outer diameter 19.3 +/- 0.04 mm, and height approximately 2.20 +/- 0.04 mm.
The LIR2025 coin cell case features a 304 stainless steel construction with a 1 µm pure aluminum coating on the positive case surface, polypropylene gasket, and precision-machined dimensions for consistent assembly in 20 mm-class battery research.
Positive
- Pure aluminum coating for corrosion resistance: 99.9% pure aluminum coating approximately 1 µm thick on the positive-case surface provides a controlled interface suitable for aluminum-compatible battery chemistries.
- Precision dimensional tolerances: Tight tolerances (e.g., ±0.04 mm on lower case height and positive case outer diameter) ensure consistent sealing and alignment during coin cell assembly.
Trade-offs
- Coating limited to positive-case surface: The pure aluminum coating is applied only to the specified positive-case surface, not the entire case, which may limit application in cells requiring full aluminum contact.
- Configuration confirmation required before ordering: Buyers must confirm coating coverage, gasket configuration, and package quantity with the supplier, adding a procurement step that may delay standard ordering.
