ELECTROCHEMICAL FLOW CAPACITORS

摘要

The present invention generally relates to devices for energy storage technologies, and more particularly to electrochemical flow capacitor systems and applications. Embodiments of this invention provide energy storage devices comprising: a positive electrode current collector, a negative electrode current collector, and an ion-permeable separator separating the positive and negative electrode current collectors;a positive electrode disposed between the positive electrode current collector and the ion-permeable separator; a negative electrode disposed between the negative electrode current collector and the ion-permeable separator; wherein at least one of the positive and negative electrodes comprises a non-stationary (including moveable or flowabie, relative to the current collectors) solid or semi-solid composition comprising supercapacitive particles and an electrolytic solvent; and wherein the electrolytic solvent is substantially free of electrochemically oxidizable or reducible species. In some embodiments, the electrodes are in electrical communication with at least a portion of the respective electrode current collector.
