TiO2 nanotube arrays,growing on three-dimensional (3D) porous Ti membrane,were synthesized using a facile nonsolvent-induced phase separation and anodization process.The length of those three-dimensional nanotube arrays could be tuned by prolonging the anodizing time.When the anodizing time is 8 h,the three-dimensional TiO2 nanotube arrays/porous Ti electrode exhibits well cycling stability and ultra-high specific capacity,which is used in lithium-ion batteries,attributed to the high utilization rate of the substrate and the high growth intensity of the active materials.Three-dimensional TiO2 nanotube arrays/porous Ti electrode,at 100 μA·cm-2 with 8 h anodizing time,shows a typical discharge plateau at 1.78 V and exhibits the specific capacity with 2126.7 μAh·cm-2.The novel nanotube arrays@3D porous architecture effectively shortens the electron/ion transmission path,which could pave way for optimizing the design of high-performance anode materials for next-generation energy storage system.
