Abstract
A pouch battery cell includes a pouch enclosure and a battery cell arranged in the pouch enclosure. A first terminal is connected to the battery cell through the pouch enclosure. A second terminal is connected to the battery cell through the pouch enclosure. A check valve includes a first gas channel in fluid communication with an inner volume of the pouch enclosure and a second gas channel. The check valve vents gas from the pouch enclosure when a difference between pressure at the first gas channel and the second gas channel is greater than a predetermined pressure difference and restricts flow of gas from the second gas channel to the first gas channel.
