Abstract
A main object of the present disclosure is to provide a battery in which wrinkles in its outer package is prevented from generating. The present disclosure achieves the object by providing a battery including: an internal element including at least a power generating element, and a laminate-type outer package in which the internal element is sealed; wherein the internal element includes a groove structure; and the battery includes a storing part where a part of the outer package is stored in the groove structure.
Claims8
A battery comprising:
- an internal element including at least a power generating element, and a laminate-type outer package in which the internal element is sealed;
- a cathode terminal extending away from the power generating element along an axis;
- and an anode terminal extending away from the power generating element along the axis opposite the cathode terminal;
- wherein:
- the internal element includes a binding member arranged on a side surface of the power generating element;
- the internal element includes a groove structure, the groove structure extends parallel to the axis, the groove structure is formed in the binding member, and the groove structure is formed in a side surface of the binding member that faces a same direction as the side surface of the of the power generating element;
- and
- the battery includes a storing part where a part of the outer package is stored in the groove structure.
A method for producing a battery that includes an internal element including at least a power generating element, and a laminate-type outer package in which the internal element is sealed, the method comprising:
- an arranging step of arranging the outer package to cover a surrounding of the internal element;
- and
- a sealing step of sealing the internal element by the outer package under a reduced pressure atmosphere, after the arranging step;
- wherein
- the battery includes a cathode terminal extending away from the power generating element along an axis and an anode terminal extending away from the power generating element along the axis opposite the cathode terminal;
- the internal element includes a binding member arranged on a side surface of the power generating element;
- the internal element includes a groove structure extending parallel to the axis, the groove structure is formed in the binding member, and the groove structure is formed in a side surface of the binding member that faces a same direction as the side surface of the of the power generating element;
- and
- the sealing step includes forming of a storing part where a part of the outer package is stored in the groove structure.
