This product is a 304 stainless steel spring sheet designed for coin cell battery assembly, serving as a critical component to ensure stable electrical contact and proper pressure within the cell casing. Available in multiple configurations—including funnel shrapnel, wave spring, and conical spring—it accommodates various standard button cell sizes such as 13 mm and 15.4 mm diameters. The spring sheets are pre-cleaned with professional solvents prior to shipment, making them ready for direct use in laboratory research or prototyping without additional surface treatment. Their corrosion-resistant material and precise dimensions support consistent performance in coin cell fabrication, particularly for energy materials testing and experimental battery setups where reliability and reproducibility are essential.
