  • AQUEOUS ENERGY STORAGE SYSTEMS WITH DESALINATION CAPABILITIES
    Publication number: 20230369662
    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.
