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.

Li -rich layer-structured x Li 2 MnO 3 ⋅ (1 - x) LiMO 2 ( M = Mn , Ni , Co , etc.) materials have attracted much attention due to their extraordinarily high reversible capacity as the cathode material in Li -ion batteries. To better understand the nature of this type of materials, this paper reviews history of development of the Li -rich cathode materials, and provides in-depth study on complicated crystal structures and reaction mechanisms during electrochemical charge/discharge cycling. Despite the fabulous capability at low rate, several drawbacks still gap this type of high-capacity cathode materials from practical applications, for instance the large irreversible capacity loss at first cycle, poor rate capability, severe voltage decay and capacity fade during electrochemical charge/discharge cycling. This review will also address mechanisms for these inferior properties and propose various possible solutions to solve above issues for future utilization of these cathode materials in commercial Li -ion batteries.

Leaves, which are very easy to obtain freely, can be used as raw materials to prepare carbon materials. In this paper, we found that hard carbon can be prepared from willow leaves by one-step carbonization. When the hard carbon was used as anode materials for Li-ion batteries, the revisable capacity of the hard carbon was 230-260 mAhg-1 at the current density of 37.2 mAg-1 with a first-cycle coulombic efficiency of about 50 %. In addition, the hard carbon shows stable cycling performance and good rate capability.
