Abstract
A desalination battery includes a working intercalation electrode in a first compartment, a counter intercalation electrode in a second compartment, both compartments including saline water solution with an elevated concentration of dissolved salts, an ion exchange membrane arranged between the compartments, a voltage source arranged to supply voltage to the electrodes, and a sacrificial compound configured to neutralize charge within the first compartment at a predetermined voltage while being consumed by oxidation or reduction reactions upon an activation of the working electrode.
