英文摘要: It is an important research issue for developing graphene-based nanocomposite electrodes used in lithium ion batteries (LIBs). We will synthesize graphene-based nanocomposites (GBNCs) via inorganic synthesis routes. The microstructrues of the as-synthesized GBNCs will be studied by X-ray diffraction, Raman spectroscopy, atomic force microscopy, transmission electron microscopy, etc., to understand the relationship between microstructure and properties. The conductivity and stability of the as-synthesized GBNCs will be controlled via changing the composition, structure, morphology of inorganic nanoparticles and graphene nanosheets. The main goal of this project is obtaing high performance electrode materials used in LIBs, and providing technical support for improved safety and long life of LIBs.
