Abstract:
There is provided an electrode assembly. The electrode assembly includes a stack of unit cells respectively including at least one negative electrode and at least one positive electrode, alternately stacked, wherein at least one separator is placed on each of both sides of the electrodes, and at least one of the unit cells has an area different from that of an adjacent unit cell to form at least one stepped portion on the electrode assembly. In addition, there are also provided a battery cell, a battery pack, and a device that include the electrode assembly.
