Abstract
Aqueous zinc-ion batteries (AZIBs) show great potential for large-scale energy storage on account of their exceptional safety, low cost, and environmental friendliness. As a representative cathode for AZIBs, commercial vanadium pentoxide (c-V2O5) still suffers from critical bottlenecks including severe vanadium dissolution, sluggish Zn2+ diffusion, and intensive interfacial side reactions in aqueous electrolytes. Herein, a novel electrochemical pretreatment strategy is developed to in-situ construct a uniform, compact ∼3 nm amorphous electrolyte interfacial layer (EIL) with an organic-inorganic composite structure on the surface of c-V2O5 in an organic lithium-ion battery system, which breaks through the limitations of unstable and inhomogeneous interfacial layers formed in conventional aqueous systems. The EIL exerts multifunctional effects by suppressing vanadium dissolution, accelerating ion diffusion, and inhibiting side reactions, endowing the modified electrode with a high initial Coulombic efficiency of 98.3%, outstanding cycling stability (180 mAh g-1 after 5000 cycles at a current density of 1 A g-1), and enhanced rate capability. This work could provide guidance for optimizing cathode materials of AZIBs through rational electrolyte interface engineering in the future.
Aqueous zinc-ion batteries (AZIBs) offer a safe, scalable path to grid storage, but their progress is limited by cathode materials that exhibit sluggish Zn2+ diffusion. Commercial vanadium pentoxide (V2O5), though possessing a high theoretical capacity, inherently suffers from this kinetic limitation. Here, a water-a...
Aqueous zinc-ion batteries (AZIBs) are regarded as appealing electrochemical storage systems because of their intrinsic safety and environmental compatibility. Nevertheless, the practical use of V2O3 cathodes remains challenging because of the intense electrostatic coupling of Zn2+ with the V2O3 crystal lattice, as w...

Aluminum-ion batteries (AIBs) are promising for large-scale energy storage owing to their elemental abundance, low cost, safety, and high anode capacity. However, their development is hindered by the limited reversibility of Al plating/stripping on Al metal anodes and cathode structural degradation under high-voltage o...
