A successful catalyst design for advanced zinc-iodine batteries
Aqueous zinc-ion batteries (ZIBs) have attracted extensive attention due to their high safety, abundant reserves, and environmental friendliness. Iodine with high abundance in seawater (55 μg L−1) is highly promising to fabricate zinc-iodine batteries due to high theoretical capacity (211 mAh g−1) and appropriate redox potential (0.54 V). However, the low electrical conductivity of iodine hinders the redox conversion for the efficient energy storage process with zinc. Additionally, the formed soluble polyiodides are prone to migirate to Zn anode, leading to capacity degration and ...
