Are Zn-iodine redox flow batteries a viable next-generation energy storage system?
Zn-iodine redox flow batteries have emerged as one of the most promising next-generation energy storage systems, due to their high energy density, low cost and superior safety. However, the low I 2 utilization and shuttle effect of iodine species greatly inhibit their practical use.
How iodine is used in a battery?
For example, in flow batteries, the generated I 2 needs to be converted into a highly soluble I 3- to avoid the deposition of elemental iodine on the electrode surface and block the electrolyte transport pathway, but in static batteries, the positive electrodes generally have strong adsorption to confine iodine to avoid shuttle effect.
Can iodine ion concentration increase battery energy density?
The above substances have a high solubility in low-corrosive neutral aqueous solutions, but the energy density of the battery cannot be infinitely increased by merely increasing the iodine ion concentration because of the zinc anode's limited area capacity and the iodine ions' low utilization rate.
Are metal-iodine batteries suitable for next-generation electrochemical energy storage systems?
Based on the works described, important and targeted guidelines in this field are provided. Metal-iodine batteries (MIBs) hold practical promise for next-generation electrochemical energy storage systems because of the high electrochemical reversibility and low cost.
