W. L. Gore & Associates has introduced the GORE Battery Vents MultiVent Series at The Battery Show North America in Detroit. This new device integrates pressure equalization, moisture protection, and thermal-runaway evacuation into a single component.
Why it matters
Traditional battery venting systems rely on multiple components, which increases design complexity and creates more potential points for moisture to enter the battery pack. By consolidating these functions, the new series simplifies sealing requirements for automotive manufacturers.
The device features an airflow of 1,200 L/h at 100 mbar and limits moisture ingress to less than 20 mg per day under controlled conditions. Its evacuation valve is designed to open at 50 mbar, providing a flow rate of 50 L/s at 180 mbar.
The players
W. L. Gore & Associates
A global material science company that employs approximately 12,000 associates and generates $5.6 billion in annual revenue.
Vernay Laboratories
A developer of fluid control and valve technologies that provided the underlying valve technology acquired by Gore in 2026.
The details
The vent utilizes two valves and a microporous membrane to manage gases and moisture through a single opening in the battery pack wall. Gore, which acquired the core valve technology from Vernay Laboratories, is currently a finalist for the 2026 Battery Pack Innovation of the Year award.
Timeline
W. L. Gore & Associates acquired core valve technology from Vernay Laboratories in 2026.
The GORE Battery Vents MultiVent Series was introduced at The Battery Show North America on October 12, 2026.
Winners of the 2026 Battery Awards will be announced on October 13, 2026.
The product will be on display at Booth 6205 from October 13 to October 15, 2026.
A technical presentation regarding the new technology is scheduled for 11:00 a.m. EDT on October 15, 2026.
Roadmap
This development represents a broader industry trend toward simplifying battery pack architecture to reduce complexity and manufacturing costs. By integrating previously separate safety systems, it positions Gore as a key supplier in the competitive EV thermal management sector.
For electric vehicle owners, this technology contributes to improved battery pack integrity and long-term durability. It potentially reduces the frequency of maintenance issues related to moisture intrusion and pressure management in high-voltage systems.
The takeaway
Consolidating battery venting components can significantly streamline the manufacturing process for electric vehicles. This integration of moisture, pressure, and thermal safety into one unit demonstrates the ongoing refinement of battery pack sealing technology.
What happens next
The 2026 Battery Awards winners will be announced on October 13, 2026, followed by a technical session on the product at 11:00 a.m. EDT on October 15, 2026.
