The structural design of a flow battery majorly consists of two sides such that each side has a storage tank, a flow field design, an electrode, a pump, a current collector, and other components. The two sides of a flow battery are commonly separated by an ion-exchange membrane, also known as separator, as shown in Fig. 1.
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.
The physicochemical properties as well as various performance metrics of organic flow batteries are significantly dependent on their major materials and design components, which include electrodes, membrane, and redox-active species/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.
Flow battery
A flow battery, or redox flow battery (after reduction–oxidation), is a type of electrochemical cell where chemical energy is provided by two chemical components dissolved in liquids that are pumped through the system on separate sides of a membrane.

DOE ESHB Chapter 6 Redox Flow Batteries
Flow batteries offer several potential safety features compared to regular, nonflowing batteries. Unlike traditional batteries, the bulk of the anolyte and catholyte are spatially separated from each other in large tanks. Thus, it is considerably harder to release all the stored energy under nonstandard or emergency conditions. Even if the electrochemical cell were to rupture, valves …
