Abstract Prussian blue analogues (PBAs) have been widely studied in aqueous zinc‐ion batteries (AZIBs) due to the characteristics of large specific surface area, open aperture, and straightforward synthesis. In this work, vanadium‐based PBA nanocubes were firstly prepared using a mild situ conversion strategy at room temperature without protection noble gas. Benefiting from multiple‐redox active sites V 3+ /V 4+ , 5+ Fe 2+ /Fe cathode exhibited an excellent discharge capacity 200 mAh g −1 AZIBs, which is much higher than those other metal‐based PBAs nanocubes. To further improve long‐term cycling stability V‐PBA cathode, high concentration water‐in‐salt electrolyte (4.5 M ZnSO 4 +3 Zn(OTf) 2 ), water‐based eutectic (5.55 glucose+3 ) designed successfully inhibit dissolution vanadium deposition Zn onto zinc anode. More importantly, assembled AZIBs maintained 55 % their highest even after 10000 cycles 10 A with superior rate capability. This study provides new for preparation pure nanostructures direction enhancing PBA‐based current densities industrialization prospects.

Rechargeable aqueous zinc-ion batteries (AZIBs) are promising energy storage systems. However, dendrite growth and side reactions on the zinc anode compromise Coulombic efficiency (CE) limit lifespan, posing constraints development of AZIBs. Herein we introduce a trifunctional additive, diethylenetriaminepentaacetic acid (DTPA), into electrolyte, which forms "shielding effect" layer surface, replaces coordinated H2O molecules in solvation sheath ions, moderates rise pH causing great enhancement reversibility cycling life anode. The Zn||Zn symmetric cell with 1.5 wt % DTPA achieves prolonged cycle 5000 h. V2O5||Zn full battery, addition DTPA, demonstrated enhanced rate performance stability.

Excessive dendrite formation and side reactions compromise the reversibility stability of zinc anodes, obstructing deployment aqueous zinc-ion batteries. An economical, yet effective solution involves deploying electrolyte additives for a solid interphase (SEI) on metal anodes. Managing to fabricate an optimal SEI via these remains challenging. Here, we introduce cost-effective copper sulfate additive, enabling creation multifunctional copper–zinc alloy SEI. The SEI's superior electrical conductivity, zincophilic sites, ample free space, elevated surface energy facilitate homogeneous Zn nucleation deposition, thereby expediting electrochemical kinetics mitigates formation.
