Designing Next-Gen Battery Packs: Gore's Newest Venting Innovation Presentation Announced


ELKTON, Md. (August 12, 2019) – W. L. Gore & Associates (Gore) announced today their participation in The Battery Show North America, to be held on September 10-12th in Novi, Michigan. Mark Weier, Gore Automotive Global Market Growth Leader, will be presenting on ways in which the GORE Low Pressure Evacuation Vent for Battery Packs enables design freedom by addressing challenges inherent in Lithium-ion battery components and packs. His presentation will be held on Wednesday, September 11th at 1:00pm in the Bronze Room.

Automotive battery components are often housed in battery packs requiring significant space, volume, and weight. In 2016, pack materials accounted for nearly 24 percent of the overall costs of a lithium-ion battery as shared at last year’s Battery Show Europe. The new GORE® Automotive Vent will enable the next generation of battery packs to be reduced in volume, weight, and cost.

"We continue to hear that designing the optimal pack with the right weight and cost profile is an ongoing challenge for battery pack designers, and the GORE Low Pressure Evacuation Vent is an exciting development for them," says Ignacio Morera, Product Manager at W. L. Gore & Associates GmbH. "They will now be able to design more reliable battery packs with thinner, lighter, and potentially lower cost materials – positively impacting driving range, the future of mobility for a world that will be hopefully cleaner, safer, and smarter."

The Battery Show North America is the country's largest trade fair for advanced battery technology, and will take place on September 10-12, 2019, in Novi, Michigan. The event attracts more than 8,500 attendees, and will be held at the Suburban Collection Showplace. Over 650 manufacturers and service providers from across the supply chain will showcase thousands of design, production and manufacturing solutions, including battery systems, materials, components, testing, and recycling.

Background

The GORE Low Pressure Evacuation Vent for Battery Packs integrates three of the most important protection functions into one solution. First, this new vent has a flexible membrane that supports a very low opening pressure of less than 2.5 kPa. Secondly, it has an over-pressure bypass function that remains reversible. This ensures prompt relief of pressure differentials in normal and severe operating conditions, which can deform lightweight housings and cause even rugged seals to fail, providing a third benefit of managing over-pressures that are associated with thermal runaway of a single cell or module.

Other protective solutions are designed to partially burst once they have reached the specified over-pressure. The result of this one-time pressure relief event is an open hole in the battery pack, which could allow moisture or other debris to enter, and potentially lead to electrical issues that could result in battery failure and thermal propagation. By combining innovative technology with a waterproof design, this new GORE Low Pressure Evacuation Vent technology facilitates pressure equalization, and enables the design of lighter, leaner battery packs without sacrificing protection against harsh environmental conditions such as water, dirt and dust.
