Development of Zinc Slurry Air Flow Battery

Choi, Nak Heon

Abstract (englisch):
Batteries have gained large interest in past few decades as energy storage systems because their merits such as relatively high efficiency, good durability of battery and unique power and energy output design. There are many types of batteries which can be used as reversible, or secondary, energy storage systems like redox flow batteries or metal-air batteries. The hybrid of those two types of batteries which is the Zinc slurry air flow battery uses zinc particles suspended in highly alkaline solution as the electrolyte and electrode for the negative compartment, whereas air is flowing in and out of the positive compartment for the oxygen reaction. As this is a relatively new concept of battery, there are two important factors which needs to be investigated. First, the discharge performance of the battery is the primary problem to be solved and the second challenge is the rechargeability of the battery to make it a secondary battery. In order to achieve those two goals, the bipolar plates are one of the key components
to be studied in redox flow batteries as they require not only a good electrical conductivity, but also good mechanical durability with high corrosion resistance. ... mehr
