Electric storage device

摘要

An electric storage device including a case, a positive electrode, a negative electrode, a current collector, a gasket, and a conductive member. The current collector has a first end connected to the positive electrode or the negative electrode and a second end electrically connected to an inner surface of the case. The conductive member includes a body and an inside large-diameter portion having a larger diameter than that of the body. The body is arranged in a mounting hole of the case. The inside large-diameter portion is disposed at one end of the body inside the case, and electrically connected to a second end of the current collector. The inside large-diameter portion is arranged so as to be in contact with an inner gasket such that the inner gasket and the second end of the current collector are sandwiched between the inside large-diameter portion and the case.

1. An electric storage device, comprising:
a case comprising a mounting hole; a positive electrode and a negative electrode housed in the case; a current collector comprising a first end and a second end, the first end being connected to one of the positive electrode and the negative electrode, the second end being in direct contact with an inner surface of the case; a gasket including an inner gasket in contact with an area of the inner surface between the mounting hole and the second end of the current collector; and a conductive member including a body and an inside large-diameter portion having a greater diameter than a diameter of the body, the body being arranged in the mounting hole of the case, the inside large-diameter portion being disposed at one end of the body inside the case, electrically connected to the second end of the current collector, and being arranged so as to be in contact with the inner gasket such that the inner gasket and the second end of the current collector are sandwiched between the inside large-diameter portion and the case.
