Abstract
Batteries having vents are disclosed. An example battery includes a housing, including: a first terminal and a second terminal. The first terminal includes a cover. The cover includes at least one line of weakness therein. The line of weakness is structured to form an opening when a threshold pressure is satisfied within the housing to enable gas to vent from the housing through the opening. A filter is positioned within the housing and adjacent the cover. The filter has an aperture structured to enable the gas to vent from the housing and to deter solid material housed within the housing from exiting the opening when the threshold pressure is satisfied.
