High-voltage and dendrite-free zinc-iodine flow battery
Researchers reported a 1.6 V dendrite-free zinc-iodine flow battery using a chelated Zn(PPi)26- negolyte. The battery demonstrated stable operation at 200 mA cm−2 over 250 cycles,
Zinc-based hybrid flow batteries are one of the most promising systems for medium- to large-scale energy storage applications, with particular advantages in terms of cost, cell voltage and energy density. Several of these systems are amongst the few flow battery chemistries that have been scaled up and commercialized.
Bifunctional zinc-air hybrid flow batteries by using propanol oxidation as a counter electrode reaction . The energy efficiency of the battery was up to c.a. 59%, which means that a percentage of energy consumed by the organic electro-synthesis can be recovered.
A number of high-surface-area electrodes, such as carbon felts and nickel foams, have been used in zinc hybrid flow batteries under acidic and alkaline conditions, . It was demonstrated that reasonable energy efficiencies (>50%) can be achieved at ultra-high current densities of up to 300 mA cm −2 .
The resulting zinc-chlorine hybrid flow battery had a practical energy density of 154 Wh kg −1, higher than that of similar zinc-bromine systems (60–85 Wh kg −1). Since the system requires additional chambers, the estimated cost was around USD$500–750/kW h, significantly higher than the DoE cost target .
