In this study, we proposed a hydrophobic liquid ionic conductive agent to mediate confined iodine transport in thick electrode, realizing highly stable zinc-iodine battery with ultra-high iodine mass loading.
Due to the high solubility, high reversibility, and low cost of iodide, iodine-based redox flow batteries (RFBs) are considered to have great potential for upscaling energy storage. However, their further development has been limited by the low capacity of I − as one-third of the I − is used to form I 3− (I 2 I −) during the charging process.
Zinc-iodine flow batteries have attracted huge attention for distributed energy storage devices owing to high inherent safety, suitable redox potential, and superior solubility.
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.
Redox flow batteries (RFBs) or flow batteries (FBs)—the two names are interchangeable in most cases—are an innovative technology that offers a bidirectional energy storage system by using redox active energy carriers dissolved in liquid electrolytes.
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.
Zinc poly-halide flow batteries are promising candidates for various energy storage applications with their high energy density, free of strong acids, and low cost . The zinc‑chlorine and zinc‑bromine RFBs were demonstrated in 1921, and 1977, respectively, and the zinc‑iodine RFB was proposed by Li et al. in 2015 .

High rate discharge of a lead acid battery refers to using its power very quickly. It could be more efficient and can shorten the battery life. Lead acid batteries are better at high-speed discharge than some other types, like lithium batteries. High-rate discharge batteries are crucial in modern tech.
Simply defined, a high-rate battery is engineered to store energy and release large bursts of that stored energy in a very short period of time. To fully grasp the technology that makes them unique, you must first understand the relationship between the battery's C Rating and its' discharge.
The discharge rate of a 100Ah battery tells you how many amps you can use in one hour. For example, if it's rated for 1C, you can safely use 100 amps in one hour. What does the discharge rate mean? Discharge rate is how quickly a battery loses its power.
