Figure 1. a. Polarization curves and b. galvanic power density as a function of current density for a substituted quinone – bromide flow battery at three different states of charge (SoC). The peak galvanic power density exceeds 0.7 W/cm2at 90% SoC.
Figure 2. Cell voltage during constant current charge-discharge cycling of a substituted quinone-bromide flow battery at ± 0.25 A/cm2. Voltage cutoffs were set at 1.3 V and 0.3 V. The time window chosen shows cycles 14-24 of a 30-cycle experiment.
