The main types of flow batteries are: Among the various types, some well-known variants include vanadium redox flow batteries (VRFBs) and zinc-based flow batteries. Flow batteries work by storing energy in chemical form in separate tanks and utilizing electrochemical reactions to generate electricity.
Flow batteries typically include three major components: the cell stack (CS), electrolyte storage (ES) and auxiliary parts. A flow battery's cell stack (CS) consists of electrodes and a membrane. It is where electrochemical reactions occur between two electrolytes, converting chemical energy into electrical energy.
