High-Conversion-Efficiency and Stable Six-Electron Zn-I2 Batteries Enabled by Organic Iodide/Thiazole-Linked Covalent Organic Frameworks

Six-electron I−/I5+ redox chemistry gives a promising platform to propel high-capacity Zn-I2 batteries, but faces limited conversion efficiency and instability of IO3− species. Here we design a thiazole-linked covalent organic...
