Flow batteries are a type of chemical energy storage where energy is stored in liquid electrolytes contained within external tanks. Unlike conventional batteries, the electrochemical reactions in flow batteries occur in the liquid state, which flows through a cell stack where the energy conversion takes place.
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.
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.
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.
Compared to lithium-ion batteries, flow batteries offer superior scalability due to their ability to easily increase energy capacity by adding more electrolytes to the tanks. Lithium-ion batteries, on the other hand, have limited scalability, as their capacity is primarily determined by the number of cells in the battery pack.
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.
Actually, the development of flow batteries can be traced back to the 1970s when Lawrence Thaller at NASA created the first prototype of this battery type. Now flow batteries haev evolved into a promising technology for certain solar energy storage applications. The schematic view of a flow battery | Source: ScienceDirect
