A device for removing chloride-containing salts from water includes a container configured to contain saline water, a first electrode arranged in fluid communication with the saline water, and a power source. The first electrode includes a conversion material that is substantially insoluble in the saline water and has a composition that includes at least two or more of aluminum, chlorine, copper, iron, oxygen, and potassium. The composition varies over a range with respect to a quantity of chloride ions per formula unit. The power source supplies current to the first electrode in a first operating state so as to induce a reversible conversion reaction in which the conversion material bonds to the chloride ions in the saline water to generate a treated water solution. The conversion material dissociates the chloride ions therefrom into the saline water solution in a second operating state to generate a wastewater solution.

The first electrode includes a conversion material that has a first composition and a second composition coexisting with the first composition. The first composition includes calcium ions bonded thereto and the second composition includes sodium ions bonded thereto. The power source supplies current in a first operating state such that the second composition exchanges sodium ions for calcium ions in the water to generate a soft water solution. The first and second electrodes are connected in a second operating state such that the first composition exchanges calcium ions for sodium ions in the water to generate a wastewater solution. The conversion material undergoes a reversible conversion reaction to convert between the first and second compositions within the water stability window.
