The opposite would look as shows: Zn ® Zn2+ + 2 e-. These certain batteries use the simple principles of any battery but changed the platform by using solutions and the exchange of electrons through an external circuit. Iron- Chromium (ICB) Flow Batteries in particular have had problems in the past such as imbalanced electrolyte solutions and membrane fouling (interference with the ion exchange), although they have had these problems they have overcome them. Porous separators have contributed to the elimination of these problems its purpose is to prevent the two electrodes from interacting. The DC/DC efficiency of this battery has been said to be in the range of 70-80%. Efficiency of this system 's performance is increased at higher operating temperatures in the range of 40-60 degrees celsius, making this RFB very suitable for warm climates. this type of power could be very helpful to underdeveloped areas near the equator due to its harsh hot/humid environment. Another battery of the Flow family is the Vanadium redox system. This system is unique due to only Vanadium being used in the reactions of oxidation and reduction. In a Vanadium exclusive system there is no need to maintain balance between positive and negative sides of the system. In the positive side of the system is the Vanadium in the form of oxy-cations the oxy-cations are vulnerable to precipitation the cannot be undone as V2O5 if the electrolyte temperature in the system exceeds ~50-60 degrees celsius. This is a major problem due to the price difference from V2O5 being around “$2.50 and Vanadium electrolyte being anywhere from $12-$25 per pound” (Vanadium Electrolyte price). So is this a system that is worth it? With the cooling system needed to keep the system under ~50-60 degrees celsius and high priced vanadium if any is lost it is expensive to replace. The final type of Flow battery is the Zinc Bromine battery
