“…The slight shifting for these V–O coordinated vibration peaks among different samples may be connected with the microscopic stress change in the crystal lattice. Besides, the absorption peaks at 1628–1633 cm −1 and 3412–3444 cm −1 could be ascribed to the bending and stretching vibrations of H–O bonds from the absorbed/bound water in samples, respectively [24,25]. The wave-number at ~2350 cm −1 is due to the contamination of CO 2 molecules in the measuring atmosphere [26].…”

One-dimensional (1D) vanadium oxide nanobelts (VOx NBs) with variable V valence, which include V3O7·H2O NBs, VO2 (B) NBs and V2O5 NBs, were prepared by a simple hydrothermal treatment under a controllable reductive environment and a following calcination process. Electrochemical measurements showed that all these VOx NBs can be adopted as promising cathode active materials for lithium ion batteries (LIBs). The Li+ storage mechanism, charge transfer property at the solid/electrolyte interface and Li+ diffusion characteristics for these as-synthesized 1D VOx NBs were systematically analyzed and compared with each other. The results indicated that V2O5 NBs could deliver a relatively higher specific discharge capacity (213.3 mAh/g after 50 cycles at 100 mA/g) and median discharge voltage (~2.68–2.71 V vs. Li/Li+) during their working potential range when compared to other VOx NBs. This is mainly due to the high V valence state and good crystallinity of V2O5 NBs, which are beneficial to the large Li+ insertion capacity and long-term cyclic stability. In addition, the as-prepared VO2 (B) NBs had only one predominant discharge plateau at the working potential window so that it can easily output a stable voltage and power in practical LIB applications. This work can provide useful references for the selection and easy synthesis of nanoscaled 1D vanadium-based cathode materials.

“…The presence of various competing interactions resulting from charge, spin, orbital, and lattice degrees of freedom can lead to many exotic properties including high-temperature superconductors, metal to insulator transition (MIT), colossal magnetoresistance, and so on. Vanadium-based compounds often reveal Mott MIT transition and represent a class of quantum materials exhibiting the most promising functionalities for the investigation of electrode materials for emerging metal-ion batteries, − emerging electrochemical energy storage, and neuromorphic circuits . Among these oxides, vanadium sesquioxide (V 2 O 3 ), often considered as a prototype Mott–Hubbard (M–H) system, is one of the most remarkable examples in correlated oxide systems .…”

Controlling the electronic properties of strongly correlated systems, observing electron–electron correlation-driven metal to insulator transition (MIT) is a key point for the next-generation solid-state Mottronic devices. Thus, the knowledge of the exact nature of the insulating state is an essential need to enhance the functionality of the material. Therefore, we have investigated the electronic nature of the insulating state of a classical Mott insulator V2O3 thin film (epitaxial) using low-temperature (LT) (120 K) resonant photoemission spectroscopy and X-ray absorption near-edge spectroscopy measurements. Temperature-dependent valence band spectra (VBS) reflect the transfer of spectral weight from the metallic coherent band (AM) near the Fermi level (E F) to the insulating Mott–Hubbard screened band (CI) at a binding energy of around 2.4 eV. Such a transfer of spectral weight upon MIT leads to vanishing of the density of states at E F and opens a band gap. The strong presence of the 3d n L final state is observed near the E F of LT VBS, confirming the presence of an O 2p band participating in low-energy charge fluctuation. This study further endorses the charge-transfer (CT)-type (U > Δ) insulating nature of a strained V2O3 thin film at LT, unlike its bulk counterpart, which is placed intermediate (U–Δ) between the CT and the Mott–Hubbard regime. Modifying the electronic ground state of V2O3 to the CT nature via the epitaxial strain in thin films provides a way to tailor the electronic energetics, with its implications to next-generation correlation-derived switching devices.
