“…The VCNF-5 electrode had a maximum energy density of 63.6 Wh kg −1 at a power density of ~400 W kg −1 , which decreased to 18.8 Wh kg −1 at a power density of 4555 W kg −1 . Velayutham et al examined the importance of electrodeposition duration on the composition of binderless VCNF electrodes [115]. Rope-like V 2 O 5 with a pure orthorhombic crystal phase was evenly deposited onto the carbon fibers, resulting in V 2 O 5 surface extrusions.…”

With the increasing energy demand for portable electronics, electric vehicles, and green energy storage solutions, the development of high-performance supercapacitors has been at the forefront of energy storage and conversion research. In the past decade, many scientific publications have been dedicated to designing hybrid electrode materials composed of vanadium pentoxide (V2O5) and carbon nanomaterials to bridge the gap in energy and power of traditional batteries and capacitors. V2O5 is a promising electrode material owing to its natural abundance, nontoxicity, and high capacitive potential. However, bulk V2O5 is limited by poor conductivity, low porosity, and dissolution during charge/discharge cycles. To overcome the limitations of V2O5, many researchers have incorporated common carbon nanostructures such as reduced graphene oxides, carbon nanotubes, carbon nanofibers, and other carbon moieties into V2O5. The carbon components facilitate electron mobility and act as porous templates for V2O5 nucleation with an enhanced surface area as well as interconnected surface morphology and structural stability. This review discusses the development of various V2O5/carbon hybrid materials, focusing on the effects of different synthesis methods, V2O5/carbon compositions, and physical treatment strategies on the structure and electrochemical performance of the composite material as promising supercapacitor electrodes.

Engineering vanadium-based materials with high conductivity, superior redox performance, and high operating voltage has attracted widespread attention in energy storage devices. Herein, we demonstrated a simple and feasible phosphorization technique to design three-dimensional (3D) network-like vanadyl pyrophosphate ((VO)2P2O7) nanowires on flexible carbon cloth (CC) (VP-CC). The phosphorization process enabled the VP-CC to increase the electronic conductivity, and the interconnected nano-network of VP-CC opens pathways for fast charge storage during the energy storage processes. Specifically, the 3D VP-CC electrodes and LiClO4 electrolyte designed as a Li-ion supercapacitor (LSC) demonstrate a maximum operating window of 2.0 V with a superior energy density (E d) of 96 μWh cm–2, power density (P d) of 10,028 μW cm–2, and outstanding cycling retention (98%) even after 10,000 cycles. In addition, a flexible LSC assembled utilizing VP-CC electrodes with a PVA/Li-based solid-state gel electrolyte exhibits a high capacitance value of 137 mF cm–2 and excellent cycling durability (86%) with a high E d of 27 μWh cm–2 and P d of 7237 μW cm–2. Considering excellent energy storage features, the highly conductive vanadium-based material has been utilized as an ideal electrode for various flexible/wearable energy storage devices with superior performance.

“…The technique avoids the usage of polymeric binders and conductive additives and reduces the overall weight of the final device, thereby increasing the gravimetric energy density. Earlier, few attempts have been made to synthesize different VO phases via electrodeposition and these have been employed for supercapacitors and rechargeable battery applications. − Ghosh et al reported electrodeposited V 2 O 5 cathodes for an aqueous zinc ion battery in the coin cell configuration; the cell has shown an impressive initial capacity of 510 mAh/g at 0.25 A/g . However, the cell lacks flexibility in design and the traditional coin cell configurations of the fabricated devices cannot support the advanced flexible electronic devices.…”

Herein we demonstrate the fabrication of a highperformance rechargeable zinc ion battery based on a laser-scribed carbon (LSC)-supported electrodeposited zinc anode and vanadium oxide (V 5 O 12 •6H 2 O) cathode with a planar-interdigitated electrode architecture and a polymeric solid electrolyte. This is the first report on a full-cell Zn//V 5 O 12 •6H 2 O planar flexible battery where a practical zinc loading (∼76 times that of the cathode loading) is maintained. The electrodeposited Zn@LSC anode showed excellent stability with very low polarization over the tested 500 h (750 cycles). We demonstrate a high initial capacity of 325 mAh/g for the Zn//V 5 O 12 •6H 2 O planar battery at 2 A/g in a 3 M ZnSO 4 aqueous electrolyte. However, the capacity dropped to 70 mAh/g only after 1000 cycles. Nonetheless, the cell performance, in particular the cycle stability, was significantly improved when the aqueous electrolyte was replaced with a gelatin/ZnSO 4 / glutaraldehyde-based solid-state electrolyte. The solid-state planar battery showed a high initial capacity of 556 mAh/g at 0.1 A/g current corresponding to an energy density of 381 Wh/kg active cathode and an impressive cycle stability with only 0.0067% capacity loss per cycle over 5500 cycles at 2 A/g. The cell also demonstrated excellent flexibility with comparable specific capacity under different bending conditions. The solid-state device exhibited a high areal energy density of 72 and 14 μWh/cm 2 at the corresponding areal power density of 130 and 2511 μW/cm 2 , respectively. Overall, the rapid (complete device fabrication in ∼2 h) and scalable fabrication approach, high performance with excellent safety features, and accompanying high flexibility make the as-fabricated Zn// V 5 O 12 •6H 2 O planar flexible battery suitable for next-generation flexible electronics applications.
