Flow battery – Wikipedia, the free encyclopedia

A flow battery is a form of rechargeable battery in which electrolyte containing one or more dissolved electroactive species flows through a Electrochemical cell that converts chemical energy directly to electricity. Additional electrolyte is stored externally, generally in tanks, and is usually pumped through the cell (or cells) of the reactor, although gravity feed systems are also known.^[1] Flow batteries can be rapidly “recharged” by replacing the electrolyte liquid (in a similar way to refilling fuel tanks for internal combustion engines) while simultaneously recovering the spent material for re-energization…

Under these definitions a flow battery is a special type of rechargeable battery in which the dissolution of active species in the electrolyte permits external storage of reactants there by allowing independent scale up of power and energy density specifications…

Flow batteries are also distinguished from fuel cells by the fact that the chemical reaction involved is often reversible, i.e. they are generally of the secondary battery type and so they can be recharged without replacing the electroactive material…
