    Abstract: A battery and an electronic device are disclosed. The battery is component to the electronic device, and includes: a first cathode plate including a first surface oriented in a first direction, and a second surface oriented in a second direction opposite to the first direction, a first separation membrane disposed on the second surface of the first cathode plate, a first anode plate disposed on a surface of the separation membrane oriented in the second direction, a through hole formed adjacent to respective center portions of the first cathode plate, the first separation membrane, and the first anode plate, wherein the through hole is substantially perpendicular to one surface of the first cathode plate, a cathode tab disposed within the through hole and electrically connected to the first cathode plate, and an anode tab spaced apart from the cathode plate within the through hole and electrically connected to the first anode plate, wherein the cathode tab and the anode tab are at least partially exposed to an external environment through the through hole.
