Redox Flow Batteries
Redox Flow BatteriesRedox flow batteries (RFB) are electrochemical ESS where two electrolyte are pumped from their own reservoirs into an electrochemical cell (the power block) where their oxidation states change according to whether the system is in charging or in discharging mode. When an electrolyte exits the power block, it is pumped to another reservoir that collects the depleted, or charged, electrolyte with its changed oxidation state. Eventually, since electrolytes are stored in reservoirs, a flow battery can be easily and quickly replenished with charged electrolyte without the need to perform a charging cycle. Normally though, charging energy comes from the feeder line of the distribution grid or the REN source to which the flow battery is connected to…
