Electron-Rich Azo Sites on Ordered Mesoporous Covalent Organic Frameworks Boosting Redox Kinetics in Aqueous Zn-I2 Batteries.
The practical application of aqueous zinc-iodine (Zn-I2) batteries is frequently hindered by the notorious shuttle effect of polyiodides and sluggish redox kinetics. To overcome these challenges, two isostructural mesoporous covalent organic frameworks (COFs) were synthesized via the condensation of 1,3,5-triformylphlo...
