Abstract: The present invention provides an ion absorption/desorption device and a corresponding method. The ion absorption device may comprise: an electrode pair (12, 14), at least one electrode of the electrode pair (12, 14) being covered by ions-permeable gel (16a) with functional groups, the gel (16a) absorbing ions in a liquid (26a) when a voltage is applied on the electrode pair (12, 14). Covering the electrode with ions-permeable gel with functional groups may facilitate chelation of the cations and/or anions in the liquid with the functional groups in the gel, thereby, immobilizing these ions in the gel so as to improve absorption efficiency.

Abstract: An energy storage system employing a reversible salination-desalination process includes an electrochemical desalination battery (EDB) unit including an anode and a cathode. The EDB unit runs a salination process while storing energy from a direct current power supply unit, and runs a desalination process while releasing energy to an electrical load. The energy storage system can store power from a variable output electrical power supply unit such as solar cells and wind turbines while running a salination process, and release energy, e.g., during peak energy demand hours while running a desalination process. Combined with a capacitive deionization (CD) unit, the energy storage system can generate fresh water by running desalination processes in the EDB unit and the CD unit while releasing stored energy from the EDB unit. The energy storage unit can function as a dual purpose device for energy storage and fresh water generation.
