ELECTRIC POWER STORAGE DEVICE
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.
