Mo─O─S‐Bridged MoS ₂ @MoO ₂ Heterostructures Enable Accelerated Zn ²⁺ Storage Kinetics in Aqueous

Layered transition metal dichalcogenides (e.g., MoS ₂ , VS ₂ ) possess intrinsic two‐dimensional diffusion channels for Zn ²⁺ , rendering them promising cathode candidates for aqueous zinc‐ion batteries (AZIBs). However, for MoS ₂ cathode, it is still challenging to unlock the limited electrochemically active sites for ideal performance. Herein, based on MoS ₂ @MoO ₂ heterostructure fabricated via a one‐step hydrothermal method, their engineered heterointerface lowers the desolvation energy via modifying the Helmholtz layer. In particular, the generation of Mo─O─S bridge bonds and abundant coordinatively unsaturated sites accelerate hydrated Zn ²⁺ migration. Consequently, the optimized MoS ₂ @MoO ₂ delivers an outstanding discharge specific capacity of 325.74 mAh g ⁻¹ at 0.1 A g ⁻¹ and an excellent capacity retention of 95.6% after 6000 cycles at 10 A g ⁻¹ .
