Abstract
Provided is a method of manufacturing an electrode assembly which is different from a stack folding method and a stack method. The method includes forming a unit structure, which comprises a stacked structure formed by sequentially stacking a first electrode, a first separator, a second electrode, and a second separator, or a structure formed by repeatedly forming the stacked structure a plurality of times (operation S), forming the electrode assembly by repeatedly stacking the unit structure into a plurality of layers (operation S), and discharging gas interposed between the layers by pressing the electrode assembly (operation S).
