Abstract: Disclosed herein is an integrated electrode assembly including a cathode, an anode, and a separation layer integrated between the cathode and the anode. The separation layer includes 3 phases including a liquid-phase component containing an ionic salt, which partially flows from the separation layer into the cathode and the anode during preparation of the integrated electrode assembly to increase ionic conductivity of the cathode and the anode, a solid-phase component supporting the separation layer between the cathode and the anode, and a polymer matrix having affinity for the liquid-phase component and providing binding force with the cathode and the anode.
