An electronic device according to an embodiment of the disclosure may include: a battery including an anode having a first length and a cathode having a second length different from the first length, a flexible printed circuit board electrically connected to the battery and surrounding at least part of a side surface of the battery, and a speaker stacked with the battery. The flexible printed circuit board may include a power wiring electrically connected to the anode and a ground wiring electrically connected to the cathode. A first current of a first winding direction generated due to a length difference between the cathode and the anode may flow in the battery, and a second current of a second winding direction opposite to the first winding direction may flow in a wiring disposed closer to the speaker between the power wiring and the ground wiring.

Battery and electronic device including the same

An electronic device including a coin-cell battery is provided. The electronic device further includes a housing, a battery comprising a first surface, a second surface, and a third surface, a first electrode disposed in the first surface and a second electrode disposed in the second surface, a first electrode tap, a second electrode tap, and a printed circuit board connecting the first electrode tap to the second electrode tap of the battery on the third surface. Soldering parts are formed on a first surface of the printed circuit board to connect an end of the first electrode tap to a first contact portion of the printed circuit board and an end of the second electrode tap to a second contact portion of the printed circuit board, respectively. A solder flow control member is formed on a second surface of the printed circuit board.
