This review provides a recent update on various strategies and perspectives for the development of aqueous zinc-iodine batteries, with a particular emphasis on the regulation of I 2 cathodes and Zn anodes, electrolyte formulation, and separator modification. . Aqueous zinc-iodine batteries (AZIBs) offer intrinsic safety, low cost, and high theoretical capacity, yet their practical performance is hindered by three coupled challenges: polyiodide shuttling that depletes active material and reduces coulombic efficiency; sluggish I 2 /I − / ( {text {I}}_. . The flow battery is one of the more interesting ideas for grid energy storage – after all, how many batteries combine electron current with fluid current? If you're interested in trying your hand at building one of these, the scientists behind the Flow Battery Research Collective just released the. . Aqueous zinc-iodine batteries stand out as highly promising energy storage systems owing to the abundance of resources and non-combustible nature of water coupled with their high theoretical capacity.
