AB  - We propose novel designs and operation strategies for redox flow batteries with the aim of higher roundtrip efficiencies (electric to chemical to electric) together with decreased amount of electrolyte. Such new designs are based on additional electrolyte tanks and compartmentalized electrodes. We analyze roundtrip efficiencies for these designs utilizing charge and discharge curves for different current densities. For commonly applied operating conditions, the results indicate that the proposed modifications and their combination result in slightly lower amount of required electrolyte and marginally higher roundtrip efficiencies as the state of the art. However, if higher per pass changes are envisaged, the savings are more significant (up to 4% higher roundtrip efficiency). A change in roundtrip efficiency has an impact on operating costs. Possible reductions in operating costs have to be contrasted with any additional investment costs and are therefore considered cumulatively as total costs. The results indicate that if higher per pass changes are envisaged, additional electrolyte tanks for setting up a two tank configuration are economically beneficial.
