A comparative overview of large-scale battery systems for electricity storage. Andreas Poullikkas, in Renewable and Sustainable Energy Reviews, 2013. 2.5 Flow batteries. A flow battery is a form of rechargeable battery in which electrolyte containing one or more dissolved electro-active species flows through an electrochemical cell that converts chemical energy directly to electricity.
The reversible conversion of chemical energy into electrical energy takes place while the liquid electrolytes flow through the battery. In ''true'' RFBs, the reaction occurs between the two electrolyte phases rather between the electrodes and the electrolytes, with the advantages of no electrodeposition nor electroactive species losses when the cell is cycled [28] .
It is discovered that the open-circuit voltage variation of an all-vanadium liquid flow battery is different from that of a nonliquid flow energy storage battery, which primarily consists of four processes: jumping down, slowly falling, slowly rising, and stabilizing.
