    摘要： Solids can sometimes form in one or more electrolyte solutions during operation of flow batteries and related electrochemical systems. Over time, the solids can accumulate and compromise the integrity of flow pathways and other various flow battery components. Flow batteries configured for mitigating solids therein can include an autonomous solids separator, such as a lamella clarifier. Such flow batteries can include a first half-cell containing a first electrolyte solution, a second half-cell containing a second electrolyte solution, a first flow loop configured to circulate the first electrolyte solution through the first half-cell, a second flow loop configured to circulate the second electrolyte solution through the second half-cell, and at least one lamella clarifier in fluid communication with at least one of the first half-cell and the second half-cell. A hydrocyclone can be used as an alternative to a lamella clarifier in some instances.

    摘要： An electrochemical cell includes a permeable fuel electrode configured to support a metal fuel thereon, and an oxidant reduction electrode spaced from the fuel electrode. An ionically conductive medium is provided for conducting ions between the fuel and oxidant reduction electrodes, to support electrochemical reactions at the fuel and oxidant reduction electrodes. A charging electrode is also included, selected from the group consisting of (a) the oxidant reduction electrode, (b) a separate charging electrode spaced from the fuel and oxidant reduction electrodes, and (c) a portion of the permeable fuel electrode. The charging electrode is configured to evolve gaseous oxygen bubbles that generate a flow of the ionically conductive medium. One or more flow diverters are also provided in the electrochemical cell, and configured to direct the flow of the ionically conductive medium at least partially through the permeable fuel electrode.

    摘要： All-vanadium sulfate redox flow battery systems have a catholyte and an anolyte comprising an aqueous supporting solution including chloride ions and phosphate ions. The aqueous supporting solution stabilizes and increases the solubility of vanadium species in the electrolyte, allowing an increased vanadium concentration over a desired operating temperature range. According to one example, the chloride ions are provided by MgCl2, and the phosphate ions are provided by (NH4)2HPO4.
