Abstract: An energy storage device includes a current collector (negative electrode current collector), electrode body that includes a body portion and a tab projecting from the body portion, and a leading plate (negative electrode leading plate) that connects the current collector and the tab. In the leading plate, first and second plates and facing each other are continuously connected at end portions thereof. In the first plate, the current collector is fixed to a first principal surface on the opposite side to the second plate. In the second plate, the tab is fixed to a second principal surface on the opposite side to the first plate.

Abstract: An energy storage device includes: an electrode body including curved portions formed by winding an electrode; a container in which the electrode body is accommodated; and a cover plate structure including a cover plate closing the container. The electrode body is accommodated in the container while one end portion in a winding axis direction of the electrode body faces the cover plate structure. The energy storage device includes spacers (side spacers) that are attached to curved portions, and one end portion of the spacer abuts on a part of the cover plate structure.

Abstract: An energy storage device includes an electrode body in which an electrode is wound, a case that stores the electrode body, and spacers (side spacers) interposed between the case and the electrode body. The spacers each have an opening that exposes a portion of faces of curved portions of the electrode body from one end to the other end of the electrode body in a winding axis direction of the electrode body.

Abstract: An energy storage device (battery) includes an electrode assembly having current collecting tabs, each of which is formed of a plurality of projecting portions, projecting from a first straight line portion on one side in a stacking direction of electrode sheets. The electrode assembly is housed in a case (exterior body). The energy storage device further includes current collectors, which are electrically connected to the external terminals, disposed on the case. The current collectors, are connected to the current collecting tabs, arranged in a stacking direction of the electrode sheets, on a second straight line portion side where the projecting portions, are not formed.
