Abstract
Various embodiments include a method for operating an electrically rechargeable redox flow battery comprising a first chamber and a second chamber separated by a membrane, with the first chamber comprising a cathode and the second chamber comprising an anode. The method comprises: introducting a first electrolyte as catholyte into the first chamber; and introducing a second electrolyte as anolyte into the second chamber. At least one of the first electrolyte or the second electrolyte comprises a reduction-oxidation pair. The oxidation number of the reduction-oxidation pair is changed by addition of a first component.
Claims6
A method for operating an electrically rechargeable redox flow battery comprising a first chamber and a second chamber separated by a membrane, with the first chamber housing a cathode and the second chamber housing an anode, the method comprising:
- introducing a first electrolyte as catholyte into the first chamber;
- introducing a second electrolyte as anolyte into the second chamber;
- wherein at least one of the first electrolyte and the second electrolyte comprises a reduction-oxidation pair;
- measuring a residual capacity of the redox flow battery;
- and
- introducing a first amount of a first component to either the first chamber or the second chamber to change an oxidation number of the reduction-oxidation pair;
- wherein the first amount depends on the measured residual capacity.
A method for operating an electrically rechargeable redox flow battery comprising a first chamber and a second chamber separated by a membrane, with the first chamber housing a cathode and the second chamber housing an anode, the method comprising:
- introducing a catholyte into the first chamber;
- introducing an anolyte into the second chamber;
- adding a first component to a first reduction-oxidation pair including a polyoxometalate in at least one of the first chamber and the second chamber;
- wherein the first component comprises at least one substance selected from the group consisting of:
- hydrazine, an alkali metal, a hydride, an aldehyde, sodium sulfite, sodium dithionite, and sodium thiosulfate.
