A Water Based Synthesis of Ultrathin Hydrated Vanadium Pentoxide Nanosheets for Lithium Battery Application: Free Standing Electrodes or Conventionally Casted Electrodes?

V2O5·nH2O nanosheets and multi-walled carbon nanotube composite as a negative electrode for sodium-ion batteries

“…In addition, the freeze drying usually increases the porosity of the V 2 O 5 •n H 2 O, which facilitates the metal ion diffusion through the material [17,26] . Our previous study showed that the best morphology of V 2 O 5 •n H 2 O and MWCNT composite can be obtained with 10% of MWCNT [24] . Here, we investigate the use of a composite of freeze dried…”

“…As a transition metal oxide, V 2 O 5 •n H 2 O has a poor electronic conductivity [23] , therefore, the addition of conducting materials (e.g. MWCNT) to form a composite electrode can increase the electronic conductivity [24] , and thus improves electrochemical performance in SIBs [25] . In addition, the freeze drying usually increases the porosity of the V 2 O 5 •n H 2 O, which facilitates the metal ion diffusion through the material [17,26] .…”

“…composite was prepared via water based approach reported earlier by us [24] . In a typical synthesis 10% of MWCNT and vanadium oxide mixture (4:1 mixture of V 2 O 5 and VO 2 ) were refluxed in water at 80 °C for 24 h. The aqueous suspension was then diluted with water in the ratio of 1:2 (i.e.…”

Flexible Freestanding MoO3−x–Carbon Nanotubes–Nanocellulose Paper Electrodes for Charge‐Storage Applications

“…recently introduced a robust synthesis protocol for the manufacturing of flexible freestanding paper electrodes by using a combination of a redox‐active material, carbon nanotubes (CNTs), and Cladophora cellulose (CC). Therefore, there is a need to explore the extension of the aforementioned synthesis approach to include some other redox‐active materials such as transition‐metal oxide nanosheets (e.g., vanadium or molybdenum oxide nanosheets) …”

Therefore, there is an eed to explore the extension of the aforementioned synthesis approach to include someo ther redox-active materials such as transition-metal oxide nanosheets (e.g.,v anadium [25][26][27] or molybdenum oxide nanosheets). [28,29] Molybdenumo xides have previously been used in av ariety of electrochemical applicationss uch as electrode materials for lithium-ion batteries, sodium-ion batteries, and supercapacitors.…”
