Process for producing electrical power from an immiscible liquid separated battery system

A process for delivering electrical power from a redox flow battery to an electrical circuit that includes an electric load, wherein the process comprises:

• selecting all of a catholyte, an anolyte and a separator liquid such that each of the catholyte and anolyte have constituents with electrochemical activity and an ion-forming supporting electrolyte and wherein the separator liquid also includes ion-forming supporting electrolyte wherein both the catholyte and the anolyte are substantially immiscible with the separator liquid thereby forming liquid-liquid interfaces but certain ions from the ion-forming supporting electrolytes in the anolyte, catholyte and separator liquid are able to pass across those liquid-liquid interfaces;
• filling a power cell with the separator liquid, the anolyte and the catholyte such that separator liquid is arranged between the anolyte and catholyte, the anolyte and the catholyte separately coexist each within its own continuous phase within the power cell such that the catholyte and anolyte are not in physical contact, but are separated within the power cell by the separator liquid which is in contact with each of the anolyte and catholyte at separate liquid-liquid interfaces;
• directing anolyte from an anolyte storage tank to the power cell where the anolyte is disposed away from the catholyte but in contact with the separator liquid while a generally corresponding volume of the anolyte in the power cell is directed out of the power cell;
• directing catholyte from a catholyte storage tank to the power cell where the catholyte is disposed away from the anolyte but in contact with the separator liquid while a generally corresponding volume of the catholyte in the power cell is directed out of the power cell;
• and
• producing electrical power by the oxidation of the electrochemical constituent of the anolyte and reduction of the electrochemical constituent of the catholyte while electrons flow from the anolyte through the electrical circuit and the certain ions move between the anolyte and catholyte through the separator liquid wherein the separator liquid remains within the power cell between the anolyte and catholyte while the anolyte and catholyte flow through the power cell and there is no ion-selective resin such as a proton exchange membrane within the redox flow battery separating any adjacent liquids.
