IntroductionWith the economic, science and technology increasing at an amazing speed, energy has become one of the most important issues in the 21 st century. In addition, the supply of fossil With revolutionary electric vehicles and the smart grid fast developing, more advanced energy storage technologies become quite crucial issues. Li-ion batteries (LIBs) and Na-ion batteries (NIBs) are considered as the most promising electrochemical energy storage technologies. Low-dimensional nano-structural electrode materials can greatly increase the specific capacity, but they still suffer from poor cycling and rate performances due to their serious self-aggregations. Constructing 3D structures, such as micro/ nano-structures and free-standing electrodes, is a quite promising method to address the above issues. Such 3D structures can simultaneously avoid the disadvantages of low-dimensional nanomaterials, and preserve their advantages. As one group of promising high-capacity and low-cost electrode materials, vanadium-based oxides have exhibited an quite attractive electrochemical performance for energy storage applications in many novel works. However, their systematic reviews are quite limited, which is disadvantageous to their further development. Herein, this article provides an overview of vanadium-based oxides in the applications of LIBs and NIBs by focusing mainly on the aspect from low-dimensional nanomaterials synthesis to 3D micro/nano-structures and free-standing electrodes fabrication. Moreover, a feasible strategy to controllably fabricate the 3D micro/nano-structure for the whole vanadium-based oxides family is presented. Furthermore, and importantly, a quite promising solution method for the practical commercialized applications of vanadium oxides cathode materials in the future is proposed, i.e., fabricating the "vanadium oxides-based cathode/solid electrolyte/Li metal anode-type" all solid-state secondary-ion batteries.

“…1 However, due to irreversibility of the crystalline phases with ion insertion and extraction, poor ionic conductivity and active material solubility in the electrolyte, modied nanostructured vanadium oxide materials 2-4 are used as a new type of electrode material.

Urchin-like vanadium oxide nanotube clusters, abbreviated to VO x -NUs, were synthesized using a new method. Vanadium pentoxide, having a layered structure, was modified by lithium fluoride (LiF) and transformed into bi-phase lithium vanadate as the inorganic precursor. Then, VO x -NUs were prepared by hydrothermal reaction with dodecylamine as a template. This is different from other molecular assembly methods reported. VO x -NUs-350 nano clusters were obtained by annealing VO x -NUs at a temperature of 350 C in air. Both samples were identified as three dimensional urchin-like nano clusters. Based on the characterization data obtained, a formation mechanism was established. By simply varying the LiF stoichiometric ratio, the nano tube density of the VO x -NUs could be controlled. VO x -NUs presented a higher initial rate capacity of 400 mA h g À1 and VO x -NUs-350 maintained a better capacity of 150 mA h g À1 after 50 cycles at a 100 mA g À1 current density between 1.5 and 4 V versus Li/Li + .
