What is a zinc iodine flow battery (zifb)?
A zinc–iodine flow battery (ZIFB) with long cycle life, high energy, high power density, and self-healing behavior is prepared. The long cycle life was achieved by employing a low-cost porous polyolefin membrane and stable electrolytes. The pores in the membrane can be filled with a solution containing I 3− that can react with zinc dendrite.
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.
Is iodine a good energy storage reaction?
Due to the insulating properties of iodine, it will bring extremely high battery polarization, and the reversibility and reaction priority are much smaller than the reaction in (2). Therefore, the reaction that generates iodine element in the flow battery is not suitable as an energy storage reaction.
What role does iodine redox chemistry play in the development of batteries?
Enhanced iodine redox chemistry and iodine species anchoring play a determining role in the advancement of zinc-iodine (Zn-I2) batteries, and it remains a major challenge to meet the application requirements with current strategies.
Are aqueous zinc-iodine batteries a promising energy storage technology?
Aqueous zinc-iodine (Zn-I 2) batteries are considered as a promising energy storage technology due to their high energy density, intrinsic safety, low cost, and resource abundance and are expected to play a key role in large-scale energy storage devices [7, 8].
