Coupling Grain Architecture Control With Oxygen‐Vacancy Suppression in Ultra‐Large Single‐ and Quasi‐Single‐Crystal Ni‐Rich Cathodes

ABSTRACT Single‐crystalline Ni‐rich layered oxide cathodes exhibit superior cycling and thermal stability over conventional polycrystalline counterparts by eliminating grain‐boundary‐associated degradation. However, the extended Li + diffusion length in single crystals limits pra...

Interhalogen Complexation Suppresses Hydrolysis–Corrosion Cross‐Talk Degradation in Aqueous Two‐Electron Zn–I 2 Batteries

ABSTRACT Aqueous two‐electron Zn–I 2 (I ‒ /I 0 /I + ) batteries offer high theoretical energy density; however, their practical operation is limited by hydrolysis of iodine monochloride (ICl), which induces cathode irreversibility and Zn‐anode degradation. Here, we introduce an e...
