Aqueous zinc-ion batteries (ZIBs) have gained attention for their safety, abundance, and environmental benefits. Iodine, found in seawater (55 μg L −1), is a promising material for zinc-iodine ...

"Trace amount of SCN ions in the bulk enter the perovskite lattice, forming an I/Br/SCN alloy, and occupy iodine vacancies, blocking halide ion migration via steric hindrance," Zhang, Chen and ...
