“…(2) The addition of metal ions can form [MO 6 ] octahedral unit structure, which can stabilize the layered structure of V 2 O 5 when Li + is insertion/extraction, and make it have better structural stability in the process of electrochemical cycling. (3) The local structural defects caused by external metal cations can be used as the nucleation center of the phase transition caused by the Li + insertion/extraction process, thus improving the electrochemical cycle stability of V 2 O 5 electrode. In addition, these structural defects can provide more paths for the diffusion of Li + .…”

“…In recent years, due to the shortage of traditional fossil energy and concerns about greenhouse gas emissions, it has become extremely important to make more effective use of energy and save limited energy in the world. At present, scientists and engineers are looking for renewable and more efficient strategies to create and store energy, so as to reduce or even avoid the impact on the environment, such as energy collected from solar heating, [1] photovoltaic power generation, [2] nuclear fission and fusion, [3] wind power generation, [4] hydropower generation, [5] and tidal fluctuation. [6] Biomass and geothermal energy [7] are favorable alternatives to traditional fossil fuel combustion.…”

Among all the known electrode materials, vanadium pentoxide (V2O5) has high reversible capacity. It is a very valuable material for research of the complexity, rich structure and morphology. However, it also has some disadvantages, such as poor cycle stability, low discharge voltage, low conductivity and Li+ diffusion coefficient. In this regard, researchers have carried out a lot of research, such as using various methods to improve the nanostructures, introducing heterostructures, introducing point defects or cation doping in the crystal structure, etc. The electrochemical performance of V2O5 has been significantly improved in reversible capacity, high-rate capacity and long-term cycle stability. In this paper, V2O5 based nanostructure with different chemical composition are briefly introduced, and it covers V2O5 nanomaterials with different morphology, including 1D nanorods, nanobelts, nanotubes, 2D leaf like nanosheets and other nanosheets, and 3D hollow structures, porous nanostructures, porous eggshell microsphere structures. The composite nanomaterials of V2O5 and different carbonaceous supports are also introduced. Finally, the V2O5 composite materials doped with cations are discussed. The electrochemical performance of V2O5 based electrode can be improved effectively by obtaining appropriate nanostructure and optimized chemical composition.
