“…Additionally, panels a and b of Figure S4 display the first three cyclic voltammetry (CV) curves at two different scan rates, 0.8 and 5.0 mV s –1 , to demonstrate the material’s stability. When we observe closely it can be clearly seen that, with the increasing scan rates, the CV curves became slightly broader, while the overall shape remained relatively unchanged without significant deviation. − The following eq determines the relationship between the peak current ( i ) and the scan rate ( v ). i = a v b where b value varies between 0.5 and 1. By fitting the obtained results in this equation, we can determine the nature of the process.…”

Aqueous zinc-ion batteries (AZIBs) have flourished as potential candidates for energy storage solutions, offering advantages like high safety, low cost, and environmental friendliness. However, their widespread application is limited by the lack of appropriate cathode materials that can operate at ultrahigh-voltage platforms and deliver enhanced performance. In this research, we investigated the potential of hydrated V 3 O 7 incorporated in a carbon network (V 3 O 7 @C) as a cathode material for AZIBs. Through a comprehensive analysis, we unveil the ultrahigh-voltage platform achieved by V 3 O 7 @C in its hydrated state, enabling superior energy storage capabilities. The hydrated V 3 O 7 @C nanosheet exhibits remarkable specific capacity, stability and Coulombic efficiency of 297.9 mAh g −1 at 0.1 A g −1 . Higher Coulombic efficiency and capacity retention of the material at 1 A g −1 are estimated to be around 95.5 and 96.5%, respectively, even after 100 cycles of charge−discharge processes in the ultrahigh-voltage platform (0−2.0 V). Furthermore, we explored the impact of H 2 O modified and C incorporated V 3 O 7 cathode material's performance and demonstrated the significant enhancement of AZIB performance. The unique combination of ultrahigh-voltage operation, stability, and enhanced performance makes the hydrated V 3 O 7 @C an attractive candidate for advancing the development of high-performance AZIBs.

The improvement of sophisticated cathode materials plays a major role in boosting the efficiency of Zn-ion batteries. These batteries have garnered considerable interest as a result of their excellent energy density and the promise of cost-effective solutions for energy storage. In this work, we present a novel approach to progress the electrochemical investigation of Zn-ion batteries by expanding the interplanar distance of layered hydrated V 2 O 3 /V 3 O 7 heterostructure nanosheets. Electrochemical investigations were conducted to assess the effectiveness of the stacked hydrated V 2 O 3 /V 3 O 7 heterostructure as a cathode component for Zn-ion batteries. The expanded interplanar space as a result of the introduction of water molecules facilitates the insertion/extraction of Zn ions, leading to significantly enhanced electrochemical characteristics. The layered hydrated V 2 O 3 /V 3 O 7 heterostructure exhibited an impressive specific capacity of 330 mAh g −1 at a current density of 0.1 A g −1 , maintaining a capacity retention of approximately 92.3% and a coulombic efficiency of 95.8% even after 2000 cycles.
