Abstract
A portable electronic device may include a housing, a display at least partially within the housing, a transparent cover over the display, and a battery at least partially within the housing. The battery may include a battery cell, a pouch encasing the battery cell, and a gas release relief system including a gas-permeable membrane configured to prevent liquid from escaping the pouch and a valve configured to selectively release gas from the pouch. The device may also include a processing system configured to, in a first mode of operation, cause the valve to open to allow gas to be released from the pouch, and, in a second mode of operation, cause the valve to close.
