This 316SS coin cell battery spacer is a stainless steel disc used inside coin cells during assembly. It measures 15.8 mm in diameter and 0.5 mm in thickness, and each piece weighs 2.83 g. It is supplied in packs of 100, 250 or 500 pieces.
The spacer keeps electrodes and separators properly aligned and helps maintain consistent internal pressure and electrical contact, so researchers can compare different electrode configurations under controlled conditions. Its solid construction gives the cell stack stability while it is being built.
Because 316 stainless steel resists corrosion, the spacer remains stable with aggressive electrolytes and through long test runs, supporting standardized, repeatable results in university labs, research institutes and battery development companies.
- Building coin cells with correctly aligned electrodes and separators.
- Laboratory-scale research on lithium-ion, sodium-ion and solid-state batteries, including evaluation of new electrode and electrolyte materials.
- Fabricating pilot-scale battery prototypes that need consistent internal pressure and electrical contact.
- Long-duration cell testing with aggressive electrolytes.
- Assembling miniature coin cells for hearing aids, smartwatches and medical implants.
