      abstract     = {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.},
