Based on the electro-active materials used in the system, the more successful pair of electrodes are liquid/gas-metal and liquid-liquid electrode systems. The commercialized flow battery system Zn/Br falls under the liquid/gas-metal electrode pair category whereas All-Vanadium Redox Flow Battery (VRFB) contains liquid-liquid electrodes.
Different aspects of materials and components in redox flow batteries should be considered, including redox-active materials (redox potential, solubility, chemical stability), (2,3) ion-conductive membranes (ion conductivity, selectivity), (4) electrodes (carbon materials, microstructure, catalytic effect), and flow field design.
Electrode is a key component for the mass transport and redox reaction in flow battery, directly determining flow battery performance.
Systems in which one or more electro-active components are stored internally are hybrid flow batteries. Examples include the zinc-bromine and the zinc-chlorine batteries in which zinc is included in the electrode design but chlorine or bromine can be fed from an external tank.
Other true flow batteries might have a gas species (for example, hydrogen, oxygen, chlorine) and/or liquid species (for example, bromine). Reversible fuel cells like hydrogen/chlorine and hydrogen/bromine, or even high temperature reversible hydrogen/oxygen solid oxide fuel cells could be thought of as flow batteries.

Flow batteries have the potential for long lifetimes and low costs in part due to their unusual design. In the everyday batteries used in phones and electric vehicles, the materials that store the electric charge are solid coatings on the electrodes.
Redox flow batteries (RFBs) or flow batteries (FBs)—the two names are interchangeable in most cases—are an innovative technology that offers a bidirectional energy storage system by using redox active energy carriers dissolved in liquid electrolytes.
“A flow battery takes those solid-state charge-storage materials, dissolves them in electrolyte solutions, and then pumps the solutions through the electrodes,” says Fikile Brushett, an associate professor of chemical engineering at MIT. That design offers many benefits and poses a few challenges. Flow batteries: Design and operation
