Aqueous organic redox-flow batteries (AORFBs) are promising for large-scale renewable energy integration due to their low-cost, high safety, material-abundant and environment-friendly features. To promote the applications, this paper builds a lifetime model to characterize an AORFB with a specific (DHBQ/K4Fe(CN)6) electrolyte, where the model characteristics are dependent on both the state of charge (SOC) and the state of health (SOH). This model serves to optimize the AORFBs development (i.e., including the electrolyte selection, volume, concentrate and proton exchange membrane size). On the other hand, it provides guidance for the power converter design to enhance the performance and integration of AORFBs. The model has been built and validated according to three charge/discharge cycling tests. According to the charge and discharge characteristics in one cycle, a photovoltaic-Storage system is built in MATLAB/Simulink to demonstrate the application of the AORFB in renewable energy systems.
