    • PURPOSE: An integrated electrode assembly is provided to prevent a shorted circuit due to the contraction of a separator, and to solve the problems of electrode non-uniformity and process time increases due to wetting by adding an electrolyte solution to an electrode. CONSTITUTION: An integrated electrode assembly comprises an electrode assembly(100), a positive electrode(110), a negative electrode(120), and a separating layer. The separating layer consists of a multi structure which comprises a two-phase electrolyte and a three-phase electrolyte. The two-phase electrolyte(140) comprises a liquid component and a polymer matrix which has a viscoelastic structure formed by a linear polymer and a cross-linked polymer in a state comprising the liquid component. The three-phase electrolyte(130) comprises a liquid component, a solid component, and a polymer matrix which has a viscoelastic structure formed by a linear polymer and a cross-lined polymer in a state comprising the liquid-phase electrolyte and the three-phase electrolyte.
