1. An electrode assembly, comprising:
two or more monocells laminated to each other, each monocell having a positive electrode, a first separator, a negative electrode, and a second separator that are sequentially laminated,
wherein another separator and another negative electrode are sequentially laminated on one of the monocells disposed at the uppermost layer of the two or more monocells laminated to each other,
wherein the another separator comprises an expansion part extending laterally to one side of the another negative electrode, and
the expansion part wraps around the monocells and the another negative electrode, the expansion part fixing the monocells and the another negative electrode to each other,
wherein a first portion of the another separator adjacent to a first end of the another separator is laminated onto a first side of the another negative electrode, and
wherein a second portion of the another separator at a second end of the another separator opposite the first end is laminated onto a second side of the another negative electrode opposite the first side.
