Ultrathin surface coating of conductive and zincophilic titanium oxynitride enables stable zinc anodes for aqueous zinc-ion batteries

The lifespan of aqueous zinc ion batteries (AZIB) has been hindered by the instability of zinc anodes, encountering challenges such as irregular dendritic growth, corrosion and hydrogen evolution reactions. In this study, we address these challenges by employing atomic-layer deposition (ALD) to create an ultrathin, conductive titanium oxynitride (TiN
