Abstract: A rechargeable battery is provided with a pressure release valve and a current interruption mechanism. The current interruption mechanism includes a deformation plate. When the internal pressure of the case reaches an interruption activation pressure, the deformation plate receives the internal pressure and is deformed to break a conducting portion. In the current interruption mechanism, a pressure that is set for maintaining the sealing at the contact portion between the deformation plate and a negative electrode conductor is defined as a sealing portion withstanding pressure, and the pressure that is set for maintaining the shape of the case is defined as a case withstanding pressure. The pressure for activating the pressure release valve is defined as a valve activation pressure. In this case, the sealing portion withstanding pressure and the valve activation pressure are set higher than the interruption activation pressure and lower than the case withstanding pressure.

Abstract: A battery pack has a sealed case. Battery modules are accommodated in the sealed case. An opening in the main body is closed by a rectangular plate-shaped lid member. The lid member has a releasing portion and a joint portion. When the internal pressure of the sealed case increases, the lid member is deformed away from an opening edge of the opening. This discharges gas from the sealed case through the releasing portion. In addition, the joint between the joint portion and the opening edge is maintained even when the internal pressure of the sealed case increases, deforming the releasing portion, and the gas inside the sealed case starts to be discharged. A protrusion of a rib is provided between the releasing portion and the joint portion.
