	Three different compositions of NiCo2S4 (NCS) materials were prepared using three solvents, named NCS HTDI (hydrothermal in DI water), NCS STEG (solvothermal in ethylene glycol), and a novel carbon-encapsulated NCS STFA (solvothermal in formamide). The structural and morphological properties of the prepared NCS HTDI, NCS STEG, and NCS HTDI materials were analyzed using various physical characterization techniques. As prepared, NCS materials were tested as an electrode for supercapacitor (SC) application using a 3-electrode system in a basic electrolyte (3 M KOH). NCS HTDI exhibits a specific capacitance of 2536 F g(-1), NCS STEG shows 1355 F g(-1), and NCS STFA shows 1178 F g(-1) at an input current density of 1 A g(-1). The SBN-PSC material is utilized as a counter electrode in the NCS STFA || SBN-PSC-based asymmetric SC device. The device exhibits exceptionally superior electrochemical performance with a specific capacitance of 172 F g(-1) at 10 A g(-1) input current density and 97\% capacity retention after 5000 cycles in a voltage window of 1.6 V. The results confirm the superiority of NCS STFA||SBN-PSC deviceas an excellent high-energy and high-power SC.</p>

	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>
