316L SS CR2032 Coin Cell Case Set (Anode and Cathode) with PP Gasket, 100 sets

316L stainless steel coin cell cases, two-piece set. Corrosion-resistant case pairs for CR2032, CR2025, CR2016 and CR2430. The molybdenum addition in 316L resists the fluoride attack that degrades 304 cases during high-voltage or long-duration cycling.

Coin cell stack order

A standard CR2032 assembly runs, from the negative case upward: negative case, spring (wave washer), spacer disc, lithium or anode disc, separator, electrolyte, cathode disc, positive case. The spring keeps the stack under constant compression as the electrodes breathe during cycling; without it, contact resistance rises and results scatter.

When 316L is worth the premium

LiPF₆ electrolyte hydrolyses in the presence of trace water to produce HF, and that attack accelerates at high voltage and elevated temperature. 304 cases can pit and discolour, which raises contact resistance and shows up as drifting impedance over hundreds of cycles. Choose 316L for cycling above 4.3 V, testing at 45 °C or higher, runs beyond a few hundred cycles, or any sulphide solid-electrolyte work. For routine graphite and LFP screening, 304 is adequate and cheaper.

Applications

• High-voltage cathode evaluation above 4.3 V
• Elevated-temperature and accelerated ageing tests
• Long-cycle life studies
• Sulphide and halide solid-state electrolyte cells
• Corrosive electrolyte and additive screening

Handling

Assemble in a dry room or argon glovebox and crimp at consistent pressure. Keep cases sealed and dry until use.
