This wave spring, also known as a Belleville washer, is made from 304 stainless steel and sized for CR2032 coin cells. Placed inside the cell stack, it applies even pressure so the electrodes stay firmly in contact throughout assembly and testing.
The part measures 15.4 mm in diameter with a thickness of 0.2 mm and a height of 1.2±0.03 mm, weighing 2.83 g. Because 304SS resists corrosion, the spring remains stable over long experiments, including those using aggressive electrolytes.
Consistent internal pressure from cell to cell helps researchers build coin cells reproducibly, which in turn makes electrochemical performance data more dependable. It is offered in packs of 100, 250 and 500 pieces.
- Assembling CR2032 coin cells with uniform pressure between the electrodes.
- Laboratory-scale research on lithium-ion and solid-state batteries, including evaluation of new electrode and electrolyte systems.
- Building pilot-scale battery prototypes that need stable internal pressure and electrical contact.
- Long-duration cell testing where corrosion resistance to aggressive electrolytes matters.
