摘要： An electrochemical device comprising an electrode assembly in which two types of electrodes are stacked or wound with separators interposed therebetween and an outer container that accommodates the electrode assembly; wherein electrode terminals extend to the outside from within the outer container. The films which cover the electrode assembly overlap each other on the outside of the outer peripheral portion of the electrode assembly, and the outer container is formed by bonding the films to each other. The portion of the films that overlap and are bonded to each other comprises a first sealed portion in which the films overlap and are bonded to each other in an overlapping state with the electrode terminals interposed therebetween, and comprises a second sealed portion in which the films are bonded to each other in a directly overlapping state without interposition of the electrode terminals.

摘要： A battery includes: an electrode body; an electrode current collector; a sealing body; an external terminal; an electrical conductor connected to the external terminal; a deforming plate sealing an opening of the electrical conductor, electrically connected to the electrical conductor and to the current collector, and deformed when an internal pressure reaches a predetermined pressure; and a first insulator between the deforming plate and the current collector. The current collector includes a base, and a lead connecting to the electrode body. First to fourth fasteners fasten the base and the first insulator. Between the first and second fasteners, the base is electrically connected to the deforming plate. The second fastener is closer to the lead than the first fastener. The second fastener is closer to a connection between the deforming plate and the electrode current collector than a position of the first insulator supported toward the sealing body.
