GORE® Automotive Vents for Li-Ion and EFB Batteries
GORE® Vents can enhance Li-Ion and lead-acid (EFB) battery performance and longevity, through effective pressure equalization and ingress protection.
Compact, Lightweight Protection for Enhanced Safety and Performance
GORE® PolyVents for easy snap-fit installation reliably protect EV battery packs and Battery Management Systems against pressure buildups while blocking ingress of damaging fluids and particles. For lead-acid applications, GORE® Catalytic Device effectively reduces electrolyte loss to improve the durability and lifetime of EFB Batteries.
For EV Battery Packs and Battery Management Systems
GORE® PolyVents
Compact, lightweight GORE® Vents for Li-Ion battery systems enable:
- 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
- Continuous airflow in and out of the enclosure
- Durable protection against liquids, dust, dirt, salts and corrosive automotive fluids
For Lead-Acid (EFB) Batteries
GORE® Catalytic Device
GORE Catalytic Device for lead-acid batteries effectively recombines hydrogen and oxygen, reducing electrolyte loss and extending battery life, as well as offering:
- Significant water loss reduction to EN 50342-1 W5 level which maintains electrolyte amounts
- Improved DCA (Dynamic Charge Acceptance) by enabling more additives to be added
- Extended battery life by maintaining electrolyte’s specific gravity
- Enhanced durability with broad temperature range (-30 ºC ~ +75 ºC)
- Snap-fit mounting for easy integration
- Potentially supports sustainability with reduced CO2 emission from battery manufacturing and recycled lead (based on initial screening LCA).
Li-Ion Battery Packs and Battery Management Systems (BMS) for EVs
Today’s EV batteries are facing demands for extended range, shorter charge times and enhanced safety, reliability and longevity. One related challenge is to prevent pressure buildup within the battery pack caused by temperature or altitude changes. GORE® Automotive Vents for batteries reduce pressure differentials with continuous airflow in and out of the enclosure, while blocking contaminants such as water, automotive fluids, salts, dirt and mud.
Lead-Acid (EFB) Batteries
The GORE® Catalytic Device is designed for use in typical manifold-type automotive lead batteries, including:
- normal/hybrid vehicles
- start-stop vehicles
Gore’s Device is also compatible with 6-plug automotive batteries. Contact your local Gore representative for additional details.
