Abstract
A secondary battery is provided and includes a first electrode wound body, a second electrode wound body, and an outer package body. The outer package body contains the first electrode wound body and the second electrode wound body. Each of the first electrode wound body and the second electrode wound body includes, at respective ends of a stacked body in a width direction, a first end face at which a first electrode is exposed and a second end face at which a second electrode is exposed. The first electrode wound body and the second electrode wound body are disposed adjacent to each other in the width direction of the stacked body, with the first end face of the first electrode wound body and the first end face of the second electrode wound body being opposed to each other.
Claims14
A secondary battery comprising:
- a first electrode wound body and a second electrode wound body each including a wound structure and each having a through hole, the wound structure including a stacked body that includes a first electrode, a second electrode, and a separator and that is wound along a longitudinal direction of the stacked body, the through hole being provided through corresponding one of the first electrode wound body and the second electrode wound body in a width direction of the stacked body orthogonal to the longitudinal direction;
- and
- an outer package body containing the first electrode wound body and the second electrode wound body, wherein
- each of the first electrode wound body and the second electrode wound body includes, at respective ends of the stacked body in the width direction, a first end face at which the first electrode is exposed and a second end face at which the second electrode is exposed, and
- the first electrode wound body and the second electrode wound body are disposed adjacent to each other in the width direction of the stacked body, with the first end face of the first electrode wound body and the first end face of the second electrode wound body being opposed to each other.
A battery pack comprising:
- a secondary battery;
- a processor configured to control the secondary battery;
- and
- an outer package member containing the secondary battery,
- the secondary battery including
- a first electrode wound body and a second electrode wound body each including a wound structure and each having a through hole, the wound structure including a stacked body that includes a first electrode, a second electrode, and a separator and that is wound along a longitudinal direction of the stacked body, the through hole being provided through corresponding one of the first electrode wound body and the second electrode wound body in a width direction of the stacked body orthogonal to the longitudinal direction, and
- an outer package body containing the first electrode wound body and the second electrode wound body, wherein
- each of the first electrode wound body and the second electrode wound body includes, at respective ends of the stacked body in the width direction, a first end face at which the first electrode is exposed and a second end face at which the second electrode is exposed, and
- the first electrode wound body and the second electrode wound body are disposed adjacent to each other in the width direction of the stacked body, with the first end face of the first electrode wound body and the first end face of the second electrode wound body being opposed to each other.
