Abstract
Provided is an electrode assembly manufacturing method including a radical unit manufacturing stage in which a radical unit having a four-layer structure is manufactured by sequentially stacking a first electrode, a first separator, a second electrode, and a second separator, and a radical unit stacking stage in which the radical unit as a unit is repeatedly stacked to manufacture an electrode assembly, and whenever a predetermined number of radical units are stacked, the radical units are adhered to each other by heating and pressing an outermost one of the radical units.
