What trade-off does the ≥96% porosity create for a nickel foam coin-cell support disc?
The ≥96% porosity with 110 ± 10 PPI pore density maximizes the open structure needed for electrolyte access and electrode contact, but also reduces the solid nickel fraction available for mechanical support. The specification compensates with defined mechanical limits, including longitudinal tensile strength ≥33.6 N/2 cm, transverse tensile strength ≥22.4 N/2 cm, and flexing endurance ≥7/15 cycles, so the disc remains robust enough for coin-cell assembly handling.
What dimensional and configuration constraints apply when integrating this nickel foam support disc into a coin cell?
The required disc diameter, thickness, and package quantity must be confirmed before ordering because this product is supplied as a cut nickel foam support disc for coin-cell internal support and electrode-contact structures. The material specification covers ≥99.99% purity, ≥96% porosity, 110 ± 10 PPI pore density, and 350 ± 25 g/m² areal density, so the selected disc geometry must match the target coin-cell internal dimensions.
What visual and handling defects should be rejected when receiving this nickel foam support disc?
Accept only discs with a clean silver-gray metallic appearance and even cut edges. Reject components showing cracks, obvious black spots, missing plating, oversized through-holes, long nickel skin, or scratches; barely visible watermarks or small spots are permitted and should not be treated as defects.
The Nickel Foam Internal Support Disc offers high porosity (>=96%) and high-purity nickel (>=99.99%) for coin cell assembly, with specified mechanical properties to ensure structural integrity. However, buyers must confirm disc dimensions and thickness prior to order, and minor surface imperfections may be present.
Positive
- High porosity and purity: Porosity >=96% and nickel purity >=99.99% ensure minimal contamination and good electrolyte wetting, critical for consistent electrochemical performance in coin cells.
- Good mechanical strength and flexibility: Longitudinal tensile strength >=33.6 N/2 cm and transverse tensile strength >=22.4 N/2 cm, with elongation and flexing cycles that provide durability during assembly and compression in battery stacks.
Trade-offs
- Requires dimensional confirmation before order: The disc diameter, thickness, and package quantity must be confirmed before ordering, adding a specification step that may delay procurement for standard needs.
- Possible minor surface imperfections: Permitted variations include barely visible watermarks or small spots, which may affect contact uniformity in high-precision applications requiring pristine surfaces.
