      abstract     = {Host-guest interactions are an attractive approach to
                      design redox electrolytes, enabling to precisely tune the
                      key properties for redox flow batteries such as half-cell
                      redox potential, solubility, and stability. Herein we report
                      a host-guest complex of highly water soluble
                      (2-hydroxypropyl)-β-cyclodextrin with
                      1-decyl-1′-ethyl-4,4′-bipyridinium dibromide as anolyte
                      in a new aqueous organic redox flow battery (AORFB). The
                      supramolecular anolyte ensured the total RFB voltage
                      increase of $≈9 \%$ up to 0.97 V and provided a stable
                      capacity delivery for more than 500 cycles with a capacity
                      fade rate of $0.037 \%/cycle$ $(2.84 \%/day)$ at high
                      Coulombic $(>99.5 \%)$ and energy $(>62 \%)$
                      efficiencies. The results highlight host-guest interactions
                      as promising strategy towards more effective storage of
                      renewable energy within AORFBs.},
