description 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 V(6)O(13) 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 V(6)O(13) for feasible Li(+) diffusion and transport and highly conductive hierarchical conductive network formed by CNT and carbon fiber in c-textile. ELECTRONIC SUPPLEMENTARY MATERIAL: The online version of this article (10.1186/s11671-018-2469-6) contains supplementary material, which is available to authorized users.
