    报告摘要:

  Hollow nanostructures are promising as electrode materials for electrochemical energy storage, including lithium-ion batteries, supercapacitors and lithium-sulfur batteries. In this talk, I will briefly discuss the design, synthesis and electrochemical properties of hollow nanostructures of metal oxides/sulfides. Specifically, we have been able to synthesize different hollow nanostructures of many binary metal oxides such as SnO2, Fe2O3 and Fe3O4, and many mixed transition metal oxides/sulfides such as NiCo2O4 and NiCo2S4. We have also designed carbon hollow structures to fabricate advanced cathode materials for lithium-sulfur batteries. Most recently, we also designed some advanced hollow structures of carbon-metal oxide including MnOx-carbon and TiOx-carbon for lithium sulfur batteries.
