Abstract
A battery and an electronic device including a battery are provided. The battery includes a case including a first face and a second face; a first unit cell including a first cathode, a first separator, and a first anode, the first anode having a characteristic of a first electrical conductivity when the first unit cell is discharged; and a plurality of second unit cells, each including a second cathode, a second separator, and a second anode, the second anode having a characteristic of a second electrical conductivity lower than the first electrical conductivity when the plurality of second unit cells are discharged. The plurality of second unit cells are disposed within the case to be adjacent to the first face and the second face, respectively, and the first unit cell is interposed between the plurality of second unit cells.
