“…Figure S2a presents the CV curves of V 2 O 3 @AC at 0.1 mV s –1 . In the third and fourth cycles, the redox peaks of 0.78/0.55 V and 1.20/1.03 V correspond to a multistep process of zinc ion storage, similar to previous reports on vanadium oxides. − It is worth noting that the peaks of the first two cycles are different and different from those of the third and fourth cycles, which can be considered as structural transformation and phase transformation. − The charge–discharge profiles also correspond to this change, as Figure S2b shows. During the first charge, there is an obvious platform near 1.33 V, which corresponded to the phase transformation.…”

Zinc ion batteries (ZIBs) have the advantages of environmental friendliness, safety, and simple assembly and have strong application potential in the field of energy storage. In this work, an amorphous carbon-loaded V2O3 (V2O3@AC) material is prepared by calcination and used as a cathode material for ZIBs. The V2O3@AC cathode has excellent stability and long life, which maintains 94.8 and 90.7% capacity retention after 180 cycles at 0.1 A g–1 and after 1600 cycles at 1 A g–1, respectively. By scanning electron microscopy (SEM) characterization, V2O3@AC is composed of small irregular nanoparticles, which have a lot of space for electrolyte penetration and ion transmission, and the kinetic studies also confirm this transport capability. The mechanism of zinc storage is studied by ex situ X-ray powder diffraction, X-ray photoelectron spectroscopy, and SEM technology, and they confirm that V2O3 will undergo phase transition and become V10O24·12H2O during the first charge process. Due to the high stability and cycle life of V2O3, we believe that it has competitive potential in zinc ion batteries and can play an important role in large-scale energy storage in the future.

The Current Developments and Perspectives of V₂O₅ as Cathode for Rechargeable Aqueous Zinc‐Ion Batteries

In recent years, zinc‐ion batteries (ZIBs) with near neutral (pH ≈ 4–6) Zn2+‐containing aqueous electrolyte have received extensive research due to their advantages of high safety, low production cost, suitable anode zinc, and environmental friendliness, etc. At present, one of the key challenges of aqueous ZIBs is the development of cathode materials with stable structure, rapid kinetics, and high capacity, etc. Compared with other cathode materials, V2O5 has an important potential application because of its high theoretical specific capacity (589 mA h g−1) based on two electron transfers, relatively low production cost, and suitable layered structure that facilitates zinc ion insertion/extraction. Herein, the following sections are proposed: 1) An understanding of the structure and energy storage mechanism of V2O5; 2) The recent development on the aqueous Zn/V2O5 battery from properties of V2O5 cathode and composition optimization of battery structure; 3) The application of V2O5 cathode in flexible ZIBs; and 4) The outlook and development trends in the future.

“…Recently, various state-of-the-art in situ analysis methods have been utilized to uncover the structural changes in electrochemical interface of V 2 O 5 electrodes such as in situ X-ray diffraction, in situ transmission electron microscopy, and in situ Raman. [9,[14][15][16] Among them, in situ spectroscopic Raman detection is a powerful and sensitive tool to understand local structural variations of the electrode-electrolyte interface for the complex electrochemical interactions during cycling. A notable example is in situ spectroscopic Raman characterization of lithium intercalation and deintercalation in thin film Li-ion battery electrodes to monitor the microstructural evolution of the LiVO system, which indicates fully reversible structural changes from the αto δ-phase, irreversible γ-phase with the permanent bond breaking, and weakly crystallized ω-phase.…”

Understanding the dynamic nature of electrochemical interface induced by ion transfer is of great significance. Herein, in situ Raman spectroscopy combined with electrochemistry has been developed to real‐time monitor the transfer of lithium ions at electrode‐electrolyte interface and reveal the associated structure and performance variation of the vanadium pentoxide (V2O5) thin films on the indium tin oxide/silver/aluminum zinc oxide/poly(ethylene terephthalate) (ITO/Ag/AZO/PET) substrates. It is demonstrated that the Raman active/silent states of the vibrational modes of VO, V3O, and VO bonds, as well as the transformation of the V2O5 thin films from V2O5 to lithium vanadate (LixV2O5), can be reversibly changed with reversible extraction/insertion of lithium ions. In situ UV‐vis spectroscopy in combination with in situ Raman analysis is applied to show that the reversible evolutions involving V2O5/LixV2O5 and VO bonding characteristic contribute to the multi‐color electrochromic characteristic of the V2O5 thin films enabling a superior optical modulation of up to 75.41%. This experimental approach establishes a significative guideline for the more elaborate research on the dynamic nature of electrochemical interface.
