Abstract
A fabricating method of an electrode assembly according to the present invention includes forming a radical unit having a four-layered structure obtained by stacking a first electrode, a first separator, a second electrode, and a second separator one by one, and stacking at least one radical unit one by one to form a unit stack part.

A fabricating method of an electrode assembly comprising:
- forming a radical unit having a four-layered structure obtained by stacking a first electrode, a first separator, a second electrode, and a second separator one by one, wherein forming the radical unit includes:
- step 1, coating the first and second separators with a coating material having adhesiveness by coating both sides of the first separator and coating both sides of the second separator;
- step 2, cutting the first electrode and the second electrode;
- step 3, attaching the first electrode, the first separator, the second electrode, and the second separator to each other by bringing the first electrode, the first separator, the second electrode and the second separator into an orientation such that the coated sides of the first separator face the first electrode and the second electrode and that one of the coated sides of the second separator faces the second electrode;
- and
- step 4, cutting the first separator and the second separator so as to be longer than the first electrode and the second electrode;
- and
- stacking at least two radical units one by one to form a unit stack part.
