Thermal-event flame screen
Battery Pack Pressure Vent Mesh (UL 2580 / IEC 62133 designs) is used for equalizing internal pressure in sealed battery enclosures and acting as a flame and spark screen at the vent if a cell goes into thermal runaway.
Also known as: battery vent mesh, metal mesh vent, pressure equalization vent mesh
Hole size: 0.10–0.20 mm etched holes quench sparks while venting gas.
Membrane stack: Pair the mesh with an ePTFE membrane for IP67 and pressure equalization.
Adhesive: High-temperature acrylic or silicone adhesive that stays bonded during venting.
Materials
Standard supply is stainless steel 304, stainless steel 316/316L; the material column in the table and the drawing options show the exact grade for each size. Other alloys and finishes can be quoted to your drawing.
Fitting & Care
Apply to a clean, primed surface and press evenly across the full adhesive ring.
Keep the vent clear of foam or harness parts inside the pack.
Common Mistakes
Using a low-temperature adhesive that lets go during a thermal event.
Omitting the metal screen, leaving the membrane alone to face flame.
When Battery Pack Pressure Vent Mesh Is Not the Right Choice
Not a burst or relief valve; large packs still need a dedicated emergency degassing valve.
Battery Pack Pressure Vent Mesh is made to order as finished parts. Indicative pricing starts from about US$0.25 per piece for a standard size at production quantity; the final price depends on size, material, finish, tooling and order volume.

Why do battery packs need vents?
Temperature and altitude changes create pressure differences that stress seals; vents equalize it.
What does the metal mesh add to a battery vent?
It acts as a spark and flame screen and protects the membrane mechanically.
Is a mesh vent waterproof?
Only when combined with a hydrophobic membrane.
What is the specification range of Battery Pack Pressure Vent Mesh?
The table on this page lists 3 standard specifications for Battery Pack Pressure Vent Mesh, from Vent u00d88 to Rect 20 u00d7 6. Specifications outside the table — custom mesh counts, wire diameters, roll widths and fabricated pieces — can be quoted on request.
