Design of flow cell of the electrochemical flow capacitor*, published in Advanced Energy Materials Journal (Adv. Energy Mater. 7/2012), is shown at the picture below.
Electrochemical Flow Cells (EFC) described by E. C. Kumbur, Y. Gogotsi, and co-workers utilizes a flowable slurry of capacitive carbon particles in an aqueous or organic electrolyte. The proposed concept combines the scalability of flow batteries with the high power density and long lifetime of electrochemical capacitors. EFC technology also decouples energy and power ratings, which is important for storage and use of energy from highly fluctuating sources. The proof-of-concept study presents promising initial performance data and discusses further development steps for this technology.
