Over the past 20 years, four designs of flow batteries have been demonstrated: vanadium redox (VRB), zinc bromine (ZnBr), polysulphide bromide (PSB) and cerium zinc (CeZn). Major installations, in Japan and North American, use the vanadium redox and zinc bromine designs. Energy efficiency is about 85% for VRB system and 75% for ZnBr system.
There are several more RFB systems currently under development, such as (i) aqueous inorganic pure flow batteries, (ii) aqueous organic redox flow batteries, (iii) pure flow membrane-less, and (iv) RFBs based on insoluble solid active materials. A summary is found in Sánchez-Díez et al. (2021).
A flow battery is an electrochemical device that converts the chemical energy of the electro-active materials directly to electrical energy, similar to a conventional battery and fuel cell. However, the electro-active materials in a flow battery are stored mostly externally and are introduced into the device only during operation.
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.
