A new type of iron-air battery is being developed as part of the project. It will have an energy density of 250 Wh/kg, an efficiency of at least 60 percent and be capable of 500 full charge/discharge cycles. To achieve this, the researchers are realizing the battery as a stack with bipolar plates. In addition, a novel galvanic manufacturing process for the iron electrode is intended to achieve a significantly higher specific capacity of the iron-air battery and thus a higher energy density.
CO2 reduction through the use of batteries?
In addition to the actual battery development, another focus of the UMSICHT scientists is the question of how much greenhouse gas minimization can be achieved by using iron-air batteries. They are looking at the use of the storage to increase the degree of self-sufficiency of photovoltaic systems.
