Document Type and Number:

WIPO Patent Application WO/2021/256770

Kind Code:

A1

Abstract:

An electronic device according to various embodiments disclosed in the present document may comprise: a jelly roll having a structure in which a positive electrode plate, a negative electrode plate, and a separator are wound together; a battery pouch for accommodating the jelly roll; a battery including a first electrode tab electrically connected to the positive electrode plate of the jelly roll and drawn out from the battery pouch, a second electrode tab electrically connected to the negative electrode plate of the jelly roll and drawn out from the battery pouch, and a sealant disposed at a portion from which the first electrode tab and the second electrode tab are drawn out from the battery pouch, and sealing the battery pouch; a printed circuit board to which the first electrode tab and the second electrode tab are electrically connected; and a sensing circuit which is positioned on the printed circuit board and can measure the state of the jelly roll, wherein the first electrode tab and the second electrode tab may extend in such a manner that at least some sections are bent so as to be electrically connected to the printed circuit board. Various other embodiments may be possible.
