  • Patent number: 11824154
    Abstract: An electrode includes a unit body stack part formed by stacking at least one basic unit having a four-layer structure in which a first electrode, a first separator, a second electrode and a second separator are sequentially stacked. Each surface of the first separator and the second separator is coated with a coating material having adhesiveness, and the basic unit adheres to an adjacent radial unit in the unit body stack part. The electrode assembly of allows a heating and pressing process to be performed prior to a primary formation process so that a separator of one basic unit and a first electrode of the other basic unit to be adhered and fixed by a coating material coated on the separator, and thus a bending phenomenon caused by a difference in electrode expansion rates in a charging/discharging process is prevented.
