“…V-based materials have longer cycle lives and better rate performances but poor discharge voltages. Additionally, in aqueous solutions, the operating voltage is relatively less (∼0.8 V) for V-based cathodes . To overcome the issues with respect to undesirable side reactions, energy density, and charge storage capacity, several strategies including doping and surface modification of the electrode and electrolytes have been employed. , In particular, V-based compounds suffer from low conductivity and poor cyclic stability, which have been mitigated by mixing with conductive materials such as reduced graphene oxide (rGO) and carbon nanotubes (CNTs). − …”

Zinc vanadium oxide (ZVO), Zn0.25V2O5·H2O, was synthesized by a facile hydrothermal synthesis and was evaluated as the positive electrode for Zn-ion batteries (ZIBs). The hydrothermal reaction time had a profound influence on the phase formation and morphology. Short reaction times (12, 24 h) lead to the formation of shorter nanobelts and secondary phases in the Zn0.25V2O5·H2O cathode. A reaction time of 48 h yielded a single-phase material with a multilayered ultralong nanobelt structure. The intercalation of water molecules into the interlayer space of ZVO increased with increasing reaction time. Cyclic voltammetry (CV) revealed that the diffusion-controlled reaction is dominant in the 48 h sample below 0.4 mV s–1 scan rate and the surface-controlled reaction is dominant above 0.4 mV s–1 scan rate. Owing to the high crystal water content and consequently increased intercalation sites, the 48 h electrode sample delivered a high capacity of 275 mAh g–1 with 99.6% coulombic efficiency at 1 C current rate and impressive cyclic stability over 200 cycles with 94% capacity retention. The 48 h electrode exhibited excellent structural and morphological stability after the Zn2+ insertion/extraction cycles, while the 24 h sample displayed degradation after the cycles as revealed by ex situ X-ray diffraction (XRD) and scanning electron microscopy (SEM) analyses. The study thus demonstrates the rate capability of ZVO and a facile synthesis route that leads to a single-phase and unique morphology, thereby providing a high-performing positive electrode for improved zinc-ion batteries.

“…To develop high-rate and long shelf-life AZIBs, many kinds of cathode materials have been successively demonstrated, which mainly includes the manganese-based oxides [4][5][6][7], vanadium-based compounds [8,9], Prussian blue analogues (PBAs) [10,11] and organic materials [12]. Among them, vanadium oxides (such as V 2 O 5 , VO 2 , V 2 O 3 ) are considered as the promising storage host due to the abundant valence state to achieve high specific capacity, and open-frameworks assembled by various coordination polyhedral to facilitate the efficient ion storage during the electrochemical cycling [13,14]. However, it has been found that such aqueous zinc-vanadium oxide battery in the acidic electrolyte usually suffers from insufficient rate performance and poor cycle lifespan (< 3000 cycles) in the research, which greatly hinders their practical applications [15,16].…”

Large volumetric expansion of cathode hosts and sluggish transport kinetics in the cathode–electrolyte interface, as well as dendrite growth and hydrogen evolution at Zn anode side are considered as the system problems that cause the electrochemical failure of aqueous Zn-vanadium oxide battery. In this work, a multifunctional anti-proton electrolyte was proposed to synchronously solve all those issues. Theoretical and experimental studies confirm that PEG 400 additive can regulate the Zn2+ solvation structure and inhibit the ionization of free water molecules of the electrolyte. Then, smaller lattice expansion of vanadium oxide hosts and less associated by-product formation can be realized by using such electrolyte. Besides, such electrolyte is also beneficial to guide the uniform Zn deposition and suppress the side reaction of hydrogen evolution. Owing to the integrated synergetic modification, a high-rate and ultrastable aqueous Zn-V2O3/C battery can be constructed, which can remain a specific capacity of 222.8 mAh g−1 after 6000 cycles at 5 A g−1, and 121.8 mAh g−1 even after 18,000 cycles at 20 A g−1, respectively. Such “all-in-one” solution based on the electrolyte design provides a new strategy for developing high-performance aqueous Zn-ion battery.

“…Therefore, developing efficient energy storage systems has become significantly important. Numerous energy storage systems with superior electrochemical performance (long cycle stability and high energy density/power density) have emerged since the first commercialization of rechargeable lithium‐ion batteries in 1990, including sodium‐ion batteries, [ 1–3 ] lithium‐sulfur batteries, [ 4–6 ] aqueous batteries, [ 7,8 ] supercapacitors, [ 9,10 ] and so on. [ 11–16 ] Meanwhile, the batteries often have extremely high energy densities, but they have a short cycle life and safety risks due to severe redox reactions and dendritic complications.…”

Zinc‐ion hybrid supercapacitors (ZHSCs) may be the most promising energy storage device alternatives for portable and large‐scale electronic devices in the future, as they combine the benefits of both supercapacitors and zinc‐ion batteries. Even though many surprise outcomes have been accomplished with ZHSCs, the creation of suitable cathode materials and electrolytes, as well as the enhancement of zinc anodes, continue to be the most difficult obstacles in the development of high‐performance ZHSCs. The low capacitance of the cathode material, poor stability, and low utilization rate of the zinc anode seriously affect the electrochemical performance and application of ZHSCs. Furthermore, parasitic processes in aqueous electrolytes, such as the hydrogen and oxygen evolution reactions might result in low‐voltage windows and unsatisfied cycling performance of the ZHSCs. This review provides a concise summary of the most recent developments and energy storage mechanisms in ZHSCs. Meanwhile, the cathode material design strategy (structural engineering, hybrid‐composite design, heteroatom doping, and so on), the zinc anode design strategy (zinc foil improvement, zinc‐free metal composites, and so on), and the structure–activity relationship of the electrochemical performance of ZHSCs are discussed. Additionally, a summary of the impact of modifications in electrolyte composition on the electrochemical performance of ZHSCs is provided. Finally, this review also discusses the future development direction of ZHSCs. It is anticipated that this evaluation will serve as a helpful reference for the creation of high‐performance ZHSCs, which will hasten the development of these devices.
