A flow battery, or redox flow battery (after reduction–oxidation), is a type of rechargeable battery where recharge ability is provided by two chemical components dissolved in liquids contained within the system and separated by a membrane. Ion exchange (providing flow of electric current) occurs through the membrane while both liquids circulate in their own respective space. Cell voltage is chemically determined by the Nernst equation and ranges, in practical applications, from 1.0 to 2.2 volts. The performance of these devices is governed by the considerations of electrochemical engineering.
The industry's leading producers are Sumitomo Electric, Dalian Rongke Power and UniEnergy Technologies, which accounted for 21.51%, 21.19% and 11.28% of revenues respectively in 2019.
