Researchers developed a novel Zn-I₂ battery design using Zn-SA-MoC/NCFs to overcome iodine’s limitations, achieving high capacity (230.6 mAh g⁻¹) and durability (90% retention after 20,000 cycles). Aqueous zinc-ion batteries (ZIBs) have gained significant attention for their high safety, widespread availability of raw materials, and environmental compatibility. Iodine, which is abundant in seawater (55 μg L−1), [...]
