Characterizations calculations confirm that dopants improve intrinsic structural stability of . Specifically, doping accelerates diffusion Zn 2+ , while formation Mn─N bonds strengthens Mn─O bonds, thereby stabilizing cycling. In addition, process creates oxygen vacancies facilitate kinetics. As result, demonstrates specific capacity 295 mAh g ‒1 at current 0.2 A exhibits 120 1 over 1500 cycles.

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 practical application. Herein, inspired by density functional theory (DFT) calculations, novel 3D sulfur vacancy‐rich heterostructured MnS/MXene aerogel is designed, used for Zn‐ion batteries/hybrid capacitors (ZIBs/ZICs) first time. Thanks synergistic modification strategy of vacancies heterostructures, as‐constructed MnS/MXene//Zn ZIBs exhibit significantly enhanced electrochemical properties, especially outstanding rate capability cyclic stability. More encouragingly, as‐assembled MnS/MXene//porous carbon (PC) ZICs an ultrahigh density, high power splendid cycling lifespan. Most notably, systematic kinetic analyses, ex situ characterizations, DFT calculations illustrate that irreversibly converts into MnO x @ZnMnO 3 /MXene, then undergoes reversible conversion from /MXene MnOOH@ZnMn 2 O 4 accompanied co‐insertion/extraction H + Zn 2+ . The heterostructures thorough mechanistic study proposed this work offer valuable guidance designing exploiting high‐performance cathodes zinc‐based devices.
