From: In situ electrochemical recomposition of decomposed redox-active species in aqueous organic flow batteries

Extended Data Fig. 3

a, Integrated areas above and below 0 V of the cell discharge voltage profile with electrochemical regeneration in Fig. 4c. b, Integrated areas above and below 0 V of the cell discharge voltage profiles with 13 regeneration processes in Fig. 4a. The area ratio (%) represents the percentage of discharged electrical energy that is subsequently used for regeneration during a single discharge process, reflecting the energetic cost. It is, on average, 1.30%. Note that the electrochemical regeneration step is not performed in every cycle, but rather once every 51 cycles. Relative to the total electricity discharged during 51 cycles, the energetic cost for regeneration is only 0.025%.
