    摘要： Provided are a method of preparing an electrode assembly suitable for preparing a secondary battery having a structure that may increase a degree of freedom in the design of a device in which the secondary battery is installed, and a method of preparing a secondary battery. The method of preparing an electrode assembly according to a first exemplary embodiment of the present invention may include the steps of: forming recessed portions recessed from edges of a first electrode and a second electrode toward inner sides thereof (S11), forming a unit structure having a four-layer structure, in which the first electrode, a first separator, the second electrode, a second separator are sequentially stacked, or a structure in which the four-layer structures are repeatedly stacked, or having the four-layer structure or a structure, in which the four-layer structures are repeatedly arranged, by stacking two kinds or more of radical units, in which the first electrode, the first separator, the second electrode, and the second separator are alternatingly disposed and integrally combined, one by one in a predetermined sequence (S20), forming recessed portions in the first separator and the second separator by cutting regions of the first separator and the second separator included in the unit structure corresponding to the recessed portions with a margin (S31), and forming an electrode assembly by stacking the plurality of unit structures to allow the recessed portions of the adjacent unit structures to face each another (S41).
