Abstract
Disclosed are a deionization electrode having ion adsorption layers and ion selective membranes formed at opposite ends thereof, an electrode module configured such that deionization electrodes are stacked, and a deionization unit having electrode modules received therein to separate ions from water. The deionization electrode includes a current collector configured to have a circular flat structure, the current collector having a first hole formed therein, a first porous adsorption layer located on one surface of the current collector, the first adsorption layer being configured to have a flat structure, a second porous adsorption layer located on the other surface of the current collector, the second adsorption layer being configured to have a flat structure, a first ion selective membrane located on the surface of the first adsorption layer, and a second ion selective membrane located on the surface of the second adsorption layer.
