Claim 8:
9. A redox flow battery system, comprising:
an anolyte,
a catholyte,
an anolyte tank configured for holding at least a portion of the anolyte,
a catholyte tank configured for holding at least a portion of the catholyte,
a primary redox flow battery arrangement comprising
a first half-cell comprising a first electrode in contact with the anolyte,
a second half-cell comprising a second electrode in contact with the catholyte,
a first separator separating the first half-cell from the second half-cell,
a first anolyte pump configured for moving the anolyte between the first half-cell and the anolyte tank,
a first catholyte pump configured for moving the catholyte between the second half-cell and the catholyte tank, and
a first electrode structure comprising a first non-conductive base having a first surface and a second surface opposite the first surface and comprising the first separator, the first electrode structure further comprising first conductive elements that extend through the first non-conductive base, wherein the first non-conductive base resists flow of anolyte and catholyte through the first non-conductive base and each of the first conductive elements comprises a first end portion exposed at the first surface of the first non-conductive base and a second end portion exposed at the second surface of the first non-conductive base, wherein the first electrode is disposed on the first surface of the first non-conductive base and the second electrode is disposed on the second surface of the first non-conductive base and wherein the first electrode comprises the first end portions of the first conductive elements and the second electrode comprises the second end portions of the first conductive elements, and

a secondary redox flow battery arrangement comprising
a third half-cell comprising a third electrode in contact with the anolyte,
a fourth half-cell comprising a fourth electrode in contact with the catholyte,
a second separator separating the third half-cell from the fourth half-cell,
a second anolyte pump configured for moving the anolyte between the third half-cell and the anolyte tank, and
a second catholyte pump configured for moving the catholyte between the fourth half-cell and the catholyte tank;

wherein a peak power delivery capacity of the secondary redox flow battery arrangement is less than a peak power delivery capacity of the primary redox flow battery arrangement.
