Components of RFBs RFB is the battery system in which all the electroactive materials are dissolved in a liquid electrolyte. A typical RFB consists of energy storage tanks, stack of electrochemical cells and flow system. Liquid electrolytes are stored in the external tanks as catholyte, positive electrolyte, and anolyte as negative electrolytes [2].
Liquid electrolytes between the electrodes ferry ions through the battery to balance the charges. The batteries can be recharged by plugging them in, which forces the charges—and the ions—to flow in reverse. But in flow batteries, the charges are stored in liquid electrolytes that sit in external tanks.
When the battery is being discharged, the transfer of electrons shifts the substances into a more energetically favorable state as the stored energy is released. (The ball is set free and allowed to roll down the hill.) At the core of a flow battery are two large tanks that hold liquid electrolytes, one positive and the other negative.
