“…Introduction To date, numerous researchers have spent great efforts in searching for transition metal oxides with diverse properties [1][2][3][4][5][6] . Vanadium oxides are a family of interesting materials with high catalytic, electrical, optical and magnetic properties and potential applications such as batteries [7][8][9][10][11][12][13][14][15][16] electrochromic devices [17][18][19][20][21][22] and thermochromic smart windows [23][24][25][26] . Indeed, the multivalent nature of vanadium cation gives it distinct colors, which earn it the name of the Norse Goddess of beauty, Vanadis.…”

In this study, vanadium sesquioxide (VO), dioxide (VO), and pentoxide (VO) were all synthesized from a single polyol route through the precipitation of an intermediate precursor: vanadium ethylene glycolate (VEG). Various annealing treatments of the VEG precursor, under controlled atmosphere and temperature, led to the successful synthesis of the three pure oxides, with sub-micrometer crystallite size. To the best of our knowledge, the synthesis of the three oxides VO, VO, and VO from a single polyol batch has never been reported in the literature. In a second part of the study, the potentialities brought about by the successful preparation of sub-micrometer VO, VO, and VO are illustrated by the characterization of the electrochromic properties of VO films, a discussion about the metal to insulator transition of VO on the basis of in situ measurements versus temperature of its electrical and optical properties, and the characterization of the magnetic transition of VO powder from SQUID measurements. For the latter compound, the influence of the crystallite size on the magnetic properties is discussed.

“…13,14 In contrast, monoclinic LiV 3 O 8 undergoes only one redox reaction (V 5+ /V 4+ ), and thus exhibits good structural reversibility during cycling. Orthorhombic LiV 2 O 5 was reported to be able to deliver a high discharge capacity of > 300 mAh g -1 , but the lithium intercalation process involves two successive redox reactions, V 5+ /V 4+ and V 4+ /V 3+ , which may lead to structural transition and capacity fade.…”

Nanoplate-stacked baguette-like LiVO₃ as a high performance cathode material for lithium-ion batteries

LiVO 3 has been proposed as an appealing cathode material to substitute traditional capacitylimited cathodes for high energy lithium-ion batteries. However, just like the other Li-V-O compounds, the application of LiVO 3 cathode is restricted by its poor cycling stability and rate capability. In this paper, we report, for the first time, nanoplates-stacked baguette-like LiVO 3 by an in situ template method. In this unique structure, the micro-sized baguette shape can help to inhibit the dissolution of vanadium in comparison with nanosized LiVO 3 , and the stacked nanoplates can provide a short diffusion pathway for lithium ions. Benefiting from these advantages, this material can deliver a very high capacity of 275.6 mAh g -1 with excellent cycling stability, Moreover, a capacity of 156.1 mAh g -1 can be obtained up to 4 C (1200 m A g -1 ). The exceptional electrochemical performance suggests the use of nanoplates-stacked baguette-like LiVO 3 as alternative cathode materials for high-energy lithium-ion batteries. Particularly, the synthesis strategy demonstrated herein may be extended to fabricate other types of multifunctional vanadium-based compounds for energy storage.

“…The same principle was followed by researchers that investigated mesoporous lithium vanadium oxide as a thin film electrode [310]. Cyclic voltammetry and galvanostatic charge/discharge cycling were used to characterize the electrochemical performance of the Li V O and V O films, deposited on FTO-coated glass.…”

Mesoporous lithium vanadium oxide as a thin film electrode for lithium-ion batteries: comparison between direct synthesis of LiV₂O₅ and electrochemical lithium intercalation in V₂O₅

Abstract: γ-LiV2O5 and α-V2O5 mesoporous thin films are prepared by a soft-templating route to compare the electrochemical performances of as-synthesized LiV2O5 with the in situ electrochemical intercalation of lithium ions in α-V2O5.
