Claim:
1. A system for the treatment of water, the system comprising at least an electrochemical desalination battery (EDB) unit comprising: at least one water chamber configured to hold water to be treated; at least one negative-ion redox electrode comprising a solution of an electrolyte material selected from cerium chloride, germanium chloride, vanadium chloride, europium chloride, and ferrous chloride, and capable of accepting, and having a reversible redox reaction with, at least one negative ion in the water; at least one positive-ion redox electrode capable of accepting, and having a reversible redox reaction with, at least one positive ion in the water, wherein the positive-ion redox electrode is immersed in the water chamber or separated from the water chamber by an optional porous separator; and an ion exchange membrane separating the at least one negative-ion redox electrode from the water chamber.
