From April 8, 2018, to June 8, 2021, the researchers randomized assigned 1,638 patients (mean age of 44.9 years) to either aqueous 10% povidone-iodine (n = 828) or aqueous 4% chlorhexidine ...

Aqueous zinc-iodine batteries offer strong safety, sustainability, and cost advantages for large-scale energy storage. However, their performance still lags behind that of lithium-ion batteries. The ...

A recent study published in Advanced Science reports a strategy to improve aqueous zinc-iodine (Zn-I 2) batteries.These batteries are valued for their low cost, safety, and long cycle life. Despite ...

Rechargeable aqueous zinc-iodine batteries get a lot of attention because they are safe, do not cost much, and have a high theoretical capacity. Zinc has a high theoretical capacity (820 mAh g-1 ...

This indicates that little electricity is stored in an aqueous battery per unit volume. Researchers employed a mixed halogen solution of iodide ions (I-) and bromide ions (Br-) as the electrolyte to ...
