Abstract
A desalination battery includes a container configured to contain a saline water solution having a first concentration c1 of dissolved salts; first and second intercalation hosts, arranged to be in fluid communication with the saline water solution, at least the first intercalation host including expanded graphite having a plurality of graphene layers with an interlayer spacing between the graphene layers in z-direction greater than 0.34 nm; and a power source configured to supply electric current to the first and second intercalation hosts such that the first and second intercalation hosts reversibly store and release cations and anions from the saline water solution located between the plurality of graphene layers to generate a fresh water solution having a second concentration c2 of dissolved salts and a brine solution having a third concentration c3 of dissolved salts within the container such that c3>c1>c2.
