Along with social progress, the popularity of portable electronic products, the development of new energy such as solar energy and wind energy technology, and the utilization of hybrid electric and electric vehicles all rely heavily on high-performance energy storage devices. Lithium ion batteries are promising storage devices to satisfy these needs due to their advantages of high open circuit voltage, large energy density, long cycle life, no memory effect, less pollution and small self-discharge rate. In fact, the capabilities of electrodes materials show significant effects on the performance of lithium-ion batteries. Nanostructured materials possess reduced sizes, enlarged surfaces, increased boundaries and gaps, which could lead to improved diffusion kinetics, more ion insert channels and release strain for volume changes compared to normal bulk materials. As electrode materials for lithium batteries, nanostructured materials could offer high reversible capacity, fine rate performance and good cycling stability. In this talk, we introduce the design and synthesis of several nanostructured materials, including MoS2-based nanocomposite, NiO porous nanostructure,Hierarchical TiO2 microstructure, and Zn2GeO4/g-C3N4 hybrids, discuss their application for lithium-ion batteries.
