Can iodine conversion chemistry be used in high-energy aqueous batteries?
To enable practical application of the bromide-iodate based iodine conversion chemistry in high-energy aqueous batteries, we further propose to use the acid-alkali decoupling electrolyte to satisfy both the anode and cathode. The proof of concept of Zn/I 2 battery in the acid-alkali decoupling electrolyte is shown in Supplementary Fig. 29.
Why do aqueous iodine-cathode batteries self-discharge?
Originated from the dissolubility of iodine and iodine species in the aqueous environment of the batteries, self-discharge behavior is common for the aqueous iodine-cathode battery systems 3, 4, 5, 6. How to reduce the self-discharge rate effectively has been an intriguing but challenging issue.
