A zinc-iron redox-flow battery under $100 per kW h of system capital cost Energy Environ. Sci., 8 ( 2015), pp. 2941 - 2945, 10.1039/c5ee02315g Chem. Rev., 115 ( 2015), pp. 11533 - 11558, 10.1021/cr500720t Toward a low-cost alkaline zinc-iron flow battery with a polybenzimidazole custom membrane for stationary energy storage
In this work, a cost model for a 0.1 MW/0.8 MWh alkaline zinc-iron flow battery system is presented, and a capital cost under the U.S. Department of Energy''s target cost of 150 $ per kWh is achieved. Besides, the effects of electrode geometry, operating conditions, and membrane types on the system cost are investigated.
It is worth noting that the working current density of alkaline Zn-Fe flow batteries is ranging from 35 to 160 mA cm−2 . In this range, the capital costs of all flow rates are under 150 $ kWh −1, which meets the DOE''s target cost for energy storage technologies.
Therefore, tremendous efforts should be made to improve the working current density, such as increasing the specific surface area of electrodes, adopting membranes with high ion conductivity, or improving the conductivity of supporting electrolytes .
