Document Type and Number:
Japanese Patent JP6778641
Kind Code:
B2
Abstract:
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.
