Automotive battery packs usually require a lot of space to package the battery components, which also makes the battery pack relatively large and heavy. In 2016, packaging materials accounted for nearly 24% of the total cost of lithium-ion batteries. The newly launched Gore battery low-voltage vent technology allows the next generation of battery packs to reduce size, weight and cost.

　　Gore's battery pack low-pressure vent technology integrates three important protection functions into one product. First of all, the new vent has a flexible membrane to support a lower opening pressure, and also has an overpressure bypass function that can reverse overpressure, ensuring that the pressure difference can be quickly released under normal and severe operating conditions of the battery, otherwise The lightweight battery casing can deform or even cause sealing failure, enabling effective management of overpressure conditions associated with thermal runaway of individual cells or battery modules. The reliability and durability of Gore's battery pack low-pressure vent technology promotes cell pressure balancing and provides critical protection from water, dirt and dust intrusion into the battery.

　　Other protective solutions, such as designs that provide a one-time pressure relief when the battery reaches a specified overpressure. This one-time pressure relief creates an opening in the battery pack that can allow moisture or other debris to enter the battery, potentially causing electrical problems such as battery failure and heat transfer. New Gore battery pack low-voltage vent technology combines innovative technology with a waterproof design to make batteries lighter while protecting them in harsh environmental conditions.
