A flow battery, or redox flow battery (after ), is a type of where is provided by two chemical components in liquids that are pumped through the system on separate sides of a membrane. inside the cell (accompanied by current flow through an external circuit) occurs across the membrane while the liquids circulate in their respective spaces.

What is the difference between a flow battery and a rechargeable battery?
The main difference between flow batteries and other rechargeable battery types is that the aqueous electrolyte solution usually found in other batteries is not stored in the cells around the positive electrode and negative electrode. Instead, the active materials are stored in exterior tanks and pumped toward a flow cell membrane and power stack.
How does a flow battery differ from a conventional battery?
In contrast with conventional batteries, flow batteries store energy in the electrolyte solutions. Therefore, the power and energy ratings are independent, the storage capacity being determined by the quantity of electrolyte used and the power rating determined by the active area of the cell stack.
How long does a flow battery last?
Flow batteries can release energy continuously at a high rate of discharge for up to 10 h. Three different electrolytes form the basis of existing designs of flow batteries currently in demonstration or in large-scale project development.
Can a battery be charged and discharged simultaneously?
There is no simultaneous charging and discharging going on. Draw out the circuit and follow the currents. You can conceptualize the above example as 1 A charging the battery and 3 A discharging it, but the battery sees the sum. Again, draw a diagram and it should be more clear. Handwaving makes everything difficult to understand.
