“…Moreover, V 6 O 13 can electrochemically incorporate up to 8 Li per formula unit, which results in a high theoretical specific capacity of 417 mA h g −1 (8 Li + intercalation).

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.

“…The main redox peaks at 2.8/2.5 V could be easily identified. Broad anodic peak at ~ 3.2 and 2.3 V and cathodic peak at ~ 1.8 V could also be observed [ 11 , 28 ]. The appearance of the above peaks indicated multi-step phase transitions, and the location of peak voltages was consistent with the previously reported ones [ 2 ].…”

Three-dimensional (3D) free-standing nanostructured materials have been proven to be one of the most promising electrodes for energy storage due to their enhanced electrochemical performance. And they are also widely studied for the wearable energy storage systems. In this work, interconnected V6O13 nanosheets were grown on the flexible carbonized textile (c-textile) via a seed-assisted hydrothermal method to form a 3D free-standing electrode for lithium-ion batteries (LIBs). The electrode exhibited a specific capacity of 170 mA h g−1 at a specific current of 300 mA g−1. With carbon nanotube (CNT) coating, its specific capacities further increased 12–40% at the various current rates. It could retain a reversible capacity of 130 mA h g−1, 74% of the initial capacity after 300 cycles at the specific current of 300 mA g−1. It outperformed most of the mixed-valence vanadium oxides. The improved electrochemical performance was ascribed to the synergistic effect of the 3D nanostructure of V6O13 for feasible Li+ diffusion and transport and highly conductive hierarchical conductive network formed by CNT and carbon fiber in c-textile.Electronic supplementary materialThe online version of this article (10.1186/s11671-018-2469-6) contains supplementary material, which is available to authorized users.
