Abstract
A battery includes a cell assembly, a pack frame accommodating the cell assembly therein, and a venting guidance portion coupled to the pack frame and configured to cause an outlet, through which venting gas emitted from the cell assembly is discharged to the outside of the pack frame, to be formed at a coupling portion with the pack frame, which is at least partially weakened as the internal pressure of the pack frame increases due to the venting gas.
