This paper focuses on the latest progress in the preparation of a series of nanostructured anode materials in our laboratory and their electrochemical properties for Li-ion batteries. These anode materials include core-shell structured Si nanocomposites, TiO2 nanocomposites, novel MoO2 anode material, and carbon nanotube (CNT)-coated SnO2 nanowires (NWs). The substantial advantages of these nanostructured anodes provide greatly improved electrochemical performance including high capacity, better cycling behavior, and rate capability.

In this work, a simple way was contrived to enhance the rate capability and cycle life of LiNixMnyCo(1-x-y)O2 by doping Zr into the material. Zr-doped LiNixMnyCo(1-x-y)O2 was synthesized by solution-based synthetic route, and its electrochemical performance was investigated as 2016 coin-type half cell. With doping, some impurity peaks appeared in the XRD pattern, which seems to be related to Zr containing oxides. The enhanced characteristics in the rate capability and cycle life might be the result of the protective effect of Zr oxide against the decomposition of electrolyte and a faster Li diffusion rate.

2-D SnO2nanosheets with controllable thickness have been synthesized via a simple hydrothermal method. Characterization shows that the sheet thickness can be controlled from 3 to 30 nm. The correlation between the sheet thickness and the electrochemical performance of these samples as anode materials for Li ion batteries were investigated, it was found that when the sheet thickness less than 10 nm, electrodes with high charge/discharge capacities, coulombic efficiencies and stable cycling performance could be realized. The good electrochemical performance are ascribe to the ultra thin nanosheet, good flexility and porous structure of the SnO2anode material.
