There are different types of flow batteries. The main types are reduction-oxidation (redox) flow batteries, membraneless flow batteries, organic flow batteries, and hybrid flow batteries. Below we explain in more detail the common main types: The most common flow battery type is the redox flow battery, or also called: true redox flow battery.
Flow batteries differ from other types of rechargeable solar batteries in that their energy-storing components—the electrolytes—are housed externally in tanks, not within the cells themselves. The size of these tanks dictates the battery's capacity to generate electricity: larger tanks mean more energy storage.
Originating in Germany, flow batteries, also called liquid flow batteries, can be categorized as a subtype of regenerative fuel cells, yet they also feature key electrochemical properties and functional principles of conventional battery cells: reversible electrochemical reactions. The structural design of a flow battery is however different.
The main advantage of flow batteries is their scalability. The energy density is basically determined by the electrolyte volume – the size of the storage tanks – as well as the surface area of the electrodes within the core. By using larger tanks that can store more electrolytes, the capacity of a flow battery can thus be easily increased.
There are major differences when comparing a flow battery vs fuel cell as they both differ in operational and functional qualities. But the major difference between both battery types is that while a flow battery can be charged and discharged accordingly, a fuel cell cannot.
