A brief review of our research in developing advanced lithium-ion battery technology is presented in this paper. We have investigated a series of novel cathode and anode materials for lithium-ion batteries with improved energy density and electrochemical performance. The cathode materials include doped LiMxMn2-xO4 spinels, LiMxNi 1-xO2 and LiMxMn1-xO2 compounds with layered structures. We have also developed numerous innovative anode lithium storage materials such as Sn-graphite composites, Cu 6Sn5, NiSi, Ni3Sn4 and FeSi 2 intermetallic alloys. The physical, structural and electrochemical properties of these newly developed electrode materials have been systematically characterized via a variety of techniques. These new electrode materials have great potential for improving the energy density of advanced lithium-ion batteries. © Institute of Materials Engineering Australasia Ltd - Materials Forum Volume 27 - Published 2004.
