Battery and electronic device including the same

An electronic device comprising:

• a battery including an anode having a first length and a cathode having a second length greater than 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,
• wherein the flexible printed circuit board includes a power wiring electrically connected to the anode and a ground wiring electrically connected to the cathode,
• wherein a first current of a first winding direction generated due to a length difference between the cathode and the anode is configured to flow in the battery, and
• wherein a second current of a second winding direction opposite to the first winding direction is configured to flow in the ground wiring disposed closer to the speaker than the power wiring.
