Utilization of renewable energy sources requires large-scale energy storage systems. Not only because its supply is timely and regionally limited, but also fluctuation of power-input can damage electrical grids. Recently, redox-targeting flow battery has been developed as a high-capacity energy storage system, which takes advantage of redox flow batteries (scalability) and solid-state batteries (energy density). Redox-targeting flow batteries are made of a heterogeneous redox-target as the main energy storage material and homogeneous redox-mediators that shuttle electrical energy between redox-target and electrochemical cell. In this study, synthesis of the insoluble polymer using a ferrocene-based, self-crosslinking monomer and the soluble shuttles was demonstrated. Also, stable cycling with high utilization of the insoluble polymer was performed in a non-aqueous condition.
