A novel solution growth of metal oxide nanocrystals within an organized surfactant matrix into mesoporous three-dimensional nanostructured frameworks with tunable mesoporosity was developed. Mesoporous crystalline transition metal oxide including CeO2, SnO2, TiO2, and composite oxide TiO2/SnO2 was synthesized. Nanostructured TiO2 has attracted much attention in Li insertion because it is not only a low voltage insertion host for Li, but also a fast Li insertion/extraction host. These characteristics render it a potential anode material for high-power lithium-ion batteries. The synthesized mesoporous crystalline TiO2 were tested as anode materials for their cycling ability and stability. The mesoporous TiO2 was able to reversibly accommodate Li up to Li0.5TiO2 (168 mA-hr/g) at 1-3 v vs. Li+/Li with excellent capacity retention and high rate capability on cycling. Other mesoporous crystalline metal oxide including composite TiO2/SnO2 was studied in terms of capacities and stability as anode materials. This is an abstract of a paper presented at the AIChE Annual Meeting (Salt Lake, UT 11/4-9/2007).
