摘要： A power storage device includes positive electrodes, negative electrodes separators each of which is located between a positive electrode and a negative electrode and insulates the positive electrode and the negative electrode from each other, and an electrode assembly, which is configured by stacking the positive electrodes, the negative electrodes, and the separators. The power storage device further includes an insulating member including sandwiching portions. Each sandwiching portion is formed by two insulating portions that sandwich a positive electrode non-application portion from both sides in the stacking direction of the electrode assembly. When viewed in the stacking direction of the electrode assembly, each insulating portion is arranged at least between a positive electrode border and a negative electrode border.

摘要： A current interruption device includes: a deforming plate configured to deform when the internal pressure of the casing rises above the predetermined level; a conducting plate which configures the current path; and a contact plate. The conducting plate includes a first contact portion configured to contact the contact plate. The contact plate includes a second contact portion configured to contact the first contact portion. The deforming plate includes a pressure receiving portion configured to receive the internal pressure of the casing and a contacting portion configured to contact the first contact portion. The second contact portion is configured to be separated from the conducting plate by deformation causing the contacting portion to move toward the contact plate. The deforming plate is insulated from the conducting plate and the contact plate. The conducting plate is disposed to be interleaved between the deforming plate and the contact plate.
