摘要： An electronic device may include a processor, and a battery configured to supply power to the processor. The battery may include multiple first electrodes including first tabs configured to protrude toward a first direction, multiple second electrodes including second tabs configured to protrude toward the first direction, and a separator configured to restrict contact between the multiple first electrodes and the multiple second electrodes. The separator may include a first separator configured to be folded in a second direction perpendicular to the first direction or a fourth direction opposite to the second direction, the first separator including multiple through-holes configured to accommodate the first tabs and the second tabs, and a second separator configured to be folded in the first direction or a third direction opposite to the first direction, the second separator being alternately stacked with the first separator. In addition, various embodiments may be possible.

摘要： A battery is provided. The battery includes a negative electrode including a first coating portion coated with a negative electrode active material and a first uncoated portion disposed adjacent to the first coating portion, a positive electrode disposed to face the negative electrode and including a second coating portion coated with a positive electrode active material and a second uncoated portion disposed adjacent to the second coating portion, a first separator disposed between one surface of the negative electrode and one surface of the positive electrode, and a second separator disposed on another surface of the negative electrode. The positive electrode, the negative electrode, and the at least one of the first separator and the second separator may be prepared in a roll shape formed by winding.
