Abstract
Disclosed is a secondary battery capable of controlling a gas discharge direction. Gas discharged to outside of the battery through a cap up may be guided in a desired direction, whereby it is possible to attach a sensor to a desired position to avoid gas discharge. In addition, it is possible to control the direction of the recoil from the discharging gas, thereby preventing and controlling problems such as damage caused by the recoil.
