In this work, flower-like SnO 2 /carbon nanotubes (CNTs) composite was synthesized by one-step hydrothermal method for high-capacity lithium storage. The microstructures of products were characterized by XRD, FESEM and TEM. The electrochemical performance of the flower-like SnO 2 /CNTs composite was measured by cyclic voltammetry and galvanostatic charge/discharge cycling. The results show that the flower-like SnO 2 /CNTs composite displays superior Li-battery performance with large reversible capacity and high rate capability. The first discharge and charge capacities are 1,230 and 842 mAh g −1 , respectively. After 40 cycles, the reversible discharge capacity is still maintained at 577 mAh g −1 at the current densities of 50, 100 and 500 mA g −1 , indicating that it’s a promising anode material for high performance lithium-ion batteries.
