摘要： An electronic device according to an embodiment of the disclosure may include a battery. The battery may include: an electrode assembly including a cathode substrate coupled to a cathode tab, an anode substrate coupled to an anode tab, and a separator sheet disposed between the cathode substrate and the anode substrate, and a pouch accommodating the electrode assembly, wherein the pouch includes a bonding portion provided along an edge of the electrode assembly, a first damage detection circuit configured to detect damage to the battery, and a circuit board to which the cathode tab, the anode tab, and the first damage detection circuit are electrically coupled. The battery may include a first portion, a second portion foldable with respect to the first portion, and a folding portion which couples the first portion and the second portion. The first damage detection circuit may extend from a first point of the circuit board to a single point of the second portion by crossing the first portion and the folding portion along an inside of the bonding portion, and extend from the single point of the second portion to a second point of the circuit board by crossing the folding portion and the first portion along the inside of the bonding portion.
