The coin cell case is designed for high-barrier protection against aggressive electrolytes in button battery assemblies. Dimensional compliance with ISO 286 tolerances is required to prevent leakage and mechanical failure during long-term testing.
- Chemical Compatibility: The 316 stainless steel construction provides corrosion resistance to common lithium battery electrolytes but must be verified against specific solvent and salt systems prior to use.
- Dimensional Tolerances: Adherence to the specified 7.85 mm diameter and 3.6 mm thickness within ISO 286 tolerance bands is critical to maintain proper sealing and electrical contact integrity.
What are the corrosion resistance trade-offs between the standard 316 stainless steel and the optional gold-plated finish in LR41 coin cell cases under aggressive electrolyte exposure?
The standard ASTM A240 grade 316 stainless steel core provides robust anti-oxidation against aggressive electrolyte solutions, making it suitable for most organic and aqueous chemistries. The optional gold plating (ASTM B456) adds a noble metal barrier that further reduces corrosion and contact resistance, which is critical for high-voltage systems or long-term cycling where even minor pitting could skew electrochemical data.
Does this 7.85 mm × 3.6 mm LR41 case integrate with standard AG3 button battery crimping dies, and what tolerance constraints must be verified?
Yes, the case is engineered to the LR41/AG3 button battery housing standard with physical dimensions of 7.85 mm diameter and 3.6 mm thickness. It is manufactured to high-precision ISO 286 tolerance criteria, ensuring uniform sealing and alignment with commercial AG3 crimping dies. Users should confirm that their die sets accommodate the 7.85 mm diameter and that the mating gaskets or spacers do not exceed the 3.6 mm stack height.
What storage and handling protocols are required to prevent premature oxidation of these 316 stainless steel coin cell cases before assembly?
Cases arrive in vacuum-sealed packages to eliminate moisture and prevent tarnishing. Before use, store all hardware in dry cabinets or sealed glovebox systems filled with ultra-pure inert gas. Technicians must wear powder-free ESD or nitrile laboratory gloves during handling to avoid lipid transfer or moisture oxidation on the active steel faces.
The ATOMFAIR 316 SS LR41 coin cell case provides high-precision geometry and robust corrosion resistance for button battery research, but mandates moisture-free storage and glove-handling to prevent surface oxidation and contamination.
Positive
- Superior Electrochemical Anti-Oxidation: Constructed from ASTM A240 grade 316 stainless steel, providing reliable defense against aggressive electrolyte solutions during long-term testing.
- High-Precision Geometry Alignment: Manufactured to strict ISO 286 tolerance criteria, ensuring uniform sealing and preventing internal assembly alignment issues in coin cell fabrication.
Trade-offs
- Moisture Sensitivity Requires Dry Storage: All hardware parts must be kept in dry cabinets or sealed glovebox systems with ultra-pure inert gas to prevent moisture-induced tarnishing or oxidation.
- Mandatory Glove Handling Protocol: Direct bare hand skin contact with active steel faces must be avoided; clean powder-free ESD or nitrile gloves are required during crimping to prevent lipid contamination and oxidation.
