Overview

Today’s batteries face demands for increasing performance, reliability and longevity. That’s true for Li-Ion technologies in EVs or Battery Management Systems, as well as for EFB (Lead-Acid) batteries. 

GORE Membrane technologies enable compact, lightweight solutions for all these applications.

SUSTAINED PROTECTION FOR ENHANCED LI-ION PERFORMANCE AND SAFETY

GORE® PolyVents for snap-fit installation reliably protect EV battery packs and Battery Management Systems, and offer added benefits:

  • A worry-free venting solution based on total quality control and our integrated design that protects the membrane
  • Easy integration without additional parts or complicated housing designs, in either plastic or metal enclosures
  • Easy installation in any process: manual, semi-automated or high-volume automated
  • Durable protection against liquids, dust, dirt, salts and corrosive automotive fluids
