    Abstract: Dual-functional energy storage systems that couple ion extraction and recovery with energy storage and release are provided. The dual-functional energy storage systems use ion-extraction and ion-recovery as charging processes. As the energy used for the ion extraction and ion recovery processes is not consumed, but rather stored in the system through the charging process, and the majority of the energy stored during charging can be recovered during discharging, the dual-functional energy storage systems perform useful functions, such as solution desalination or lithium-ion recovery with a minimal energy input, while storing and releasing energy like a conventional energy storage system.

    Abstract: Tandem electrodialysis (ED) cell systems and methods for using the tandem ED cell systems to extract and recover ions from ion-containing solutions are provided. The tandem ED cell systems are composed of ion-extraction and ion-recovery ED cells. A redox couple contained in the anolyte of the ion-extraction ED cell is different from a redox couple contained in the catholyte of the ion-extraction ED cell. The electrode reactions in the ion-extraction ED cell are reversed in the ion-recovery ED cell, with the anolyte and catholyte of the two ED cells swapped and continuously circulated. As a result, the redox species in the anolyte and catholyte of the two cells are never depleted, which allows for achieving ion extraction and ion recovery with the use of a minimal amount of the redox couples.

    Abstract: Bismuth-based, chloride-storage electrodes and rechargeable electrochemical cells incorporating the chloride-storage electrodes are provided. Also provided are methods for making the electrodes and methods for using the electrochemical cells to remove chloride ions from a sample. The chloride-storage electrodes, which are composed of bismuth metal, can store chloride ions in their bulk by forming BiOCl via an oxidation reaction with bismuth in the presence of an oxygen source.

    Abstract: Electrochemical systems and methods for removing and recovering phosphorus, in the form of phosphates, from aqueous solutions are provided. The removal of the phosphates takes place in an electrochemical cell having an electrode that includes bismuth (Bi), zinc (Zn), copper (Cu), iron (Fe), or an oxide thereof. During the removal of phosphates from aqueous solution, the metal (Bi, Zn, Cu, or Fe) and/or metal oxide of the electrode is converted into its corresponding metal phosphate within the electrode via a reversible conversion reaction. The phosphate stored in the electrode during the removal step is subsequently released into a recovery solution via electrochemical reduction of the metal phosphate back into a metal.
