A few-layered MoS 2 -C composite material is studied as a supporting material for silicon nanopowder. Microspheres of the few-layered MoS 2 -C composite embedded with 30 wt.% Si nanopowder are prepared by one-pot spray pyrolysis. The Si nanopowder particles with high capacity are completely surrounded by the few-layered MoS 2 -C composite matrix. The discharge capacities of the MoS 2 -C composite microspheres with and without 30 wt.% Si nanopowder after 100 cycles are 1,020 and 718 mAh·g -1 at a current density of 1,000 mA·g -1 , respectively. The spherical morphology of the MoS 2 -C composite microspheres embedded with Si nanopowder is preserved even after 100 cycles because of their high structural stability during cycling. The MoS 2 -C composite layer prevents the formation of unstable solid-electrolyte interface (SEI) layers on the Si nanopowder. Furthermore, as the MoS 2 -C composite matrix exhibits high capacity and excellent cycling performance, these characteristics are also reflected in the MoS 2 -C composite microspheres embedded with 30 wt.% Si nanopowder.

Graphene-molybdenum dioxide composites in several ratios have been prepared through a facile synthesis method. Depending on the ratio, the as synthesized composites have either 2-dimensional graphene sheets with MoO 2 particles anchored to them or a clustered agglomerate morphology. The composites have been characterised using Raman spectroscopy, X-ray diffraction, and electron diffraction to confirm the monoclinic MoO 2 phase that is present. Lithium storage properties of the assynthesised samples were tested in a coin-type half cell assembly to determine the relationship between the ratio and the electrochemical performance. The sample with highest amount of MoO 2 (78 wt%) displayed the most promising lithium storage properties, with stable cycling performance at 0.2 A g À1 that shows negligible capacity loss over 50 cycles, retaining a capacity of 640 mA h g À1. The rate capabilities were also tested, and show a capacity of 380 mA h g À1 at 2.0 A g À1, which is comparable to the theoretical capacity of graphite and previously reported work on similar materials.

There is tremendous worldwide interest in functional nanostructured materials, which are the advanced nanotechnology materials with internal or external dimensions on the order of nanometers. Their extremely small dimensions make these materials unique and promising for clean energy applications such as lithium ion batteries, supercapacitors, hydrogen storage, fuel cells, and other applications. This paper will highlight the development of new approaches to study the relationships between the structure and the physical, chemical, and electrochemical properties of functional nanostructured materials. The Energy Materials Research Programme at the Institute for Superconducting and Electronic Materials, the University of Wollongong, has been focused on the synthesis, characterization, and applications of functional nanomaterials, including nanoparticles, nanotubes, nanowires, nanoporous materials, and nanocomposites. The emphases are placed on advanced nanotechnology, design, and control of the composition, morphology, nanostructure, and functionality of the nanomaterials, and on the subsequent applications of these materials to areas including lithium ion batteries, supercapacitors, hydrogen storage, and fuel cells.
