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.
The chemical energy is converted to the electric energy when the electrolytes flow through the external tanks. The volume of the electrolyte and the surface area of the electrode influence the performance of the flow battery. Flow batteries can be employed both as a rechargeable secondary battery and a fuel cell.
Flow battery design can be further classified into full flow, semi-flow, and membraneless. The fundamental difference between conventional and flow batteries is that energy is stored in the electrode material in conventional batteries, while in flow batteries it is stored in the electrolyte.
Other flow-type batteries include the zinc–cerium battery, the zinc–bromine battery, and the hydrogen–bromine battery. A membraneless battery relies on laminar flow in which two liquids are pumped through a channel, where they undergo electrochemical reactions to store or release energy. The solutions pass in parallel, with little mixing.
Hybrid flow batteries incorporate one solid electrode along with a flowing electrolyte. This solid electrode, often made from a metal, stores energy through plating and de-plating processes, similar to how traditional batteries function. A popular example is the Zinc-Bromine flow battery.
Electrolytes are stored externally in tanks, while the electrochemical cell handles energy conversion. Flow batteries have two main categories: Redox flow batteries utilize redox reactions of the electrolyte solutions for energy storage.
