A rechargeable battery includes an electrode assembly including a positive electrode including a positive current collector, a positive active material on the positive current collector in a positive coating region, and a positive uncoated region in which the positive active material is not on the positive current collector at a first side of the electrode assembly; a negative electrode including a negative current collector, a negative active material on the negative current collector in a negative coating region, a first negative uncoated region in which the negative active material is not on the negative current collector at the first side of the electrode assembly, and a second negative uncoated region in which the negative active material is not on the negative current collector at a second side of the electrode assembly opposite the first side; and a separator between the positive electrode and the negative electrode.
