	Aqueous zinc-ion batteries (ZIBs) offer several compelling advantages as a safer and sustainable energy storage system. Polyanion-based cathodes, characterized by their comparatively higher voltage and structural stability, are promising for ZIBs. However, challenges hinder their practical applications, such as inferior rate capability and limited cycling stability. In this study, we constructed a carbon nanotube wrapped Na3V2(PO4)2F3 (NVPF-CNT) cathode integrated with a highly concentrated dual cation electrolyte (DCE) to enhance the electrochemical performance of ZIBs by enabling a synergistic Na+ and Zn2+ co-insertion mechanism. The DCE effectively regulates the solvation structure, stabilizes the solid electrolyte interface (SEI), minimizes free water molecules, thereby widening the electrochemical window and reducing the side reactions, and inhibits cathode dissolution. Consequently, the CNT-wrapped NVPF cathode exhibits an initial reversible capacity of 131.3 mAh g-1 at 0.05 A g-1, and retains 84\% of its capacity over 500 cycles at 1 A g-1, with a nominal voltage of similar to 1.5 V. This approach offers valuable insights into the potential of CNT-wrapped NVPF cathodes in combination with a DCE while providing a comprehensive framework for advancing high-performance ZIBs.</p>

	An efficient bifunctional oxygen electrocatalyst, a nickel-iron metal organic framework (NF-MOF) grown within three-dimensional (3D) nitrogen doped porous carbon (NPC) collectively referred as NF-MOF@NPC, is developed as high performance electrocatalyst for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). The synergistic effect of bimetallic active sites coupled with conductive nitrogen doped porous carbon matrix, provides chemical stability, abundant active sites, enhanced electron transfer, and improve catalytic activity. NFMOF@NPC exhibits OER onset potential of 1.60 V at current density of 10 mA cm- 2 with Tafel slope of 126 mV dec- 1 and ORR half wave potential of 0.81 V with electron transfer number of 3.91. A zinc-air battery fabricated using NF-MOF@NPC shows peak power density of 102 mW cm-2 and specific capacity of 741 mAh g-Z 1n. It also exhibits remarkable cycling stability for 120 h at current density of 10 mA cm- 2 highlighting its promise as alternative for conventional platinum on carbon (Pt/C) and ruthenium dioxide (RuO2) electrocatalysts demonstrating its potential for next generation energy storage devices.</p>
