Abstract

A desalination battery includes a first electrode, a second electrode, an intercalation compound contained in the first electrode, a container configured to contain a saline water solution, and a power source. The intercalation compound includes at least one of a metal oxide, a metalloid oxide, a metal oxychloride, a metalloid oxychloride, and a hydrate thereof with each having a ternary or higher order. The first and second electrodes are configured to be arranged in fluid communication with the saline water solution. The power source is configured to supply electric current to the first and second electrodes in different operating states to induce a reversible intercalation reaction within the intercalation compound. The intercalation compound reversibly stores and releases target anions from the saline water solution to generate a fresh water solution in one operating state and a wastewater solution in another operating state.
