报告摘要：

In recentyears, transition metal oxides have been extensively investigated as negativematerials in lithium ion batteries due to their high specific capacity. Amongthem, ZnO is thought to be a promising anode material for lithium ion batteriesdue to its outstanding merits including high theoretical capacity of 987 mAhg-1, low cost, abundant resources, environmentally friendly, as well asexcellent lithium ion diffusion coefficients in comparison with othertransition metal oxides. However, they are faced with the problems to realizetheir commercial applications due to the inherent drawbacks of low electronicconductivity and huge volume change during charge/discharge. In this talk, Iwill discuss our progress in the development of ZnO-based materials to tacklethe above-mentioned challenges during the last 3 years for energy storage.
