摘要	Electrodes with three-dimensional (3D) nanostructure are expected to improve the energy and power densities of lithium ion batteries. Herein, we report a 3D porous Ti/SnO2 nanocomposite which was prepared by a novel experimental procedure combining the dealloying technique and hydrothermal treatment. Its structure and electrochemical properties were investigated with scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) analysis, X-ray photoelectron spectroscopy (XPS), energy dispersive X-ray (EDX) spectroscopy and galvanostatic charge-discharge tests. The results of electrochemical tests showed that the porous composite anode presented the largest reversible capacity of 616.0 mA h g(-1) at the first cycle; and it still delivered a reversible Li storage capacity of 432.5 mA h g(-1) after 100 cycles. Our work suggests the possibility of further improving the specific capacity/energy density of 3D microelectrodes by designing ordered hybrid nanostructure arrays. (C) 2014 Elsevier B.V.
