A facile and elegant self-organization strategy is proposed to decorate V2O5 nanosheets with Ag nanoparticles and TiO2 nanorods simultaneously.

Lightweight, interconnected VO2 nanoflowers hydrothermally grown on 3D graphene networks for wide-voltage-window supercapacitors

“…14 Among various oxides, vanadium oxides has been suggested as one of the most promising pseudocapacitance electrode materials due to its high energy density, low cost, and wide potential windows, arising from vanadium multivalent states 4+ , and V 5+ ). 15,16 Based on the basic principle of energy storage, the nanostructures of vanadium oxides become an inevitable way to improve the performance of supercapacitors. The various nanostructures of vanadium oxides for supercapacitors had been realized, such as nanobelts, 17 nanoakes, 18 nanowires, 19 nanotextiles.…”

Y-doped V2O5 with enhanced lithium storage performance

“…To overcome these drawbacks, numerous efforts have been carried out. Some groups prepared V 2 O 5 with various nanostructures, such as nanorods, 12,13 nanoribbons, 14,15 nanowires, [16][17][18] nanosheets, [19][20][21][22] porous/hollow spheres, [23][24][25] and even hierarchical/ heterogonous nanostructures. 26,27 These nanostructured materials showed enhanced electrochemical kinetics, specic capacity, and rate performance than the pristine V 2 O 5 due to their small size and large surface area, which could greatly increase the contact area between active materials and electrolyte, shorten the diffusion pathways of Li + , and relax the mechanical stress associated Li + intercalation/deintercalation.…”

Atomic layer deposited V2O5 coatings: a promising cathode for Li-ion batteries

“…Nevertheless, one of the key obstacles encountered in the commercialization of LIBs is the development of electrode materials. In particular, the determining factor for the overall energy density of LIBs is the capacity of the cathode, which is lower than that of the anode [4]. Hence, it is important to find cathodes with high reversibility, high rate capability and extended cycle stability.…”
