Abstract:
Aqueous zinc-ion batteries (ZIBs) are bottlenecked by vanadium-based cathodes with inferior conductivity, sluggish Zn2+ transport, and structural instability. Herein, we design Zn-doped V2O3@C (Zn-V2O3@C) nanorods via MOF-derived annealing, integrating Zn evaporation-coupled doping and V2O3@C heterostructure engineering. The V2O3@C heterointerface with a built-in electric field (BIEF) accelerates internal electron transfer; residual Zn dopants (Zn: V = 0.037) induce lattice expansion (unit cell volume expanded by 1.51 Å3 after doping) and oxygen vacancies, narrowing the band gap to 0.56 eV and reducing Zn2+ diffusion barrier to 0.12 eV, which synergistically optimizes electronic structure and ion transport kinetics. Given the aforementioned strategies, the cathode delivers superior rate capability, with 422.8 mAh g-1 at 0.2 A g-1 and 265.8 mAh g-1 even at 10.0 A g-1. This versatile evaporation-doping strategy serves as a valuable reference for modulating high-performance ZIB cathodes.
