Anion Vacancies Coupling with Heterostructures Enable Advanced Aerogel Cathode for Ultrafast Aqueous Zinc‐Ion Storage

Abstract As a potential cathode material, manganese‐based sulfide has recently attracted increasing interest due to its many advantages in aqueous zinc‐ion storage. Unfortunately, some challenges such as sluggish kinetics, unstable structure, and controversial phase transition mechanism during the energy storage process hinder its practical application. Herein, inspired by density functional theory (DFT) calculations, a novel 3D sulfur vacancy‐rich and heterostructured MnS/MXene aerogel is designed, and used as a cathode for aqueous Zn‐ion batteries/hybrid capacitors (ZIBs/ZICs) for the first time. Thanks to the synergistic modification strategy of sulfur vacancies and heterostructures, the as‐constructed…
