1. An intercalation electrode for a desalination battery, comprising:
an intercalation compound that contains 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 intercalation compound configured to be at least partially immersed in a saline water solution and undergo a reversible intercalation reaction in which (i) anions from the saline water solution reversibly insert within the intercalation compound in a first condition of the electrode and (ii) the anions within the intercalation compound de-insert therefrom into the saline water solution in a second condition of the electrode,
wherein the intercalation compound has the chemical formula MAxOy·zH2O, where M=Al, Ca, Co, Cr, Cu, Fe, Mg, Mn, Mo, Na, Nb, Ni, Si, Ti, V, W, Zr, or a combination thereof, A=Br, Cl, F, I, N, P, or a combination thereof, and 0<x, y, z<7.
