A Long‐Life and Excellent Rate‐Capability Aqueous Zn‐Benzoquinone Battery Enabled by Iodine‐Catalyzed Cathode

Benzoquinone (BQ) is considered to be a desirable cathode material for aqueous zinc-based batteries. The major limitations of BQ electrode are the severe sublimation and poor electrical conductivity, which results in serious mass loss during electrode preparation and inferior rate performance. In this study, iodine (I
