제목 High-rate capability of hollow spherical titanium dioxide as negative electrode materials for lithium-ion batteries.
초록 Hollow spherical TiO2 powders are prepared from the TDIP(titanium diisopropoxide acetylacetonate) precursor by PS(polystyrene) nanosphere template. These hollow spherical TiO2 powders with thin wall thickness (~20 nm) showed better electrochemical characteristics than that of commercial TiO2 nanopowders with 100 nm particle size. Low-crystalline TiO2 hollow sphere synthesized at 500oC shows higher specific capacity of 190 mAh/g (@0.1 C-rate) and TiO2 hollow sphere heat-treated at 700oC has excellent rate capability with slightly high crystallinity.
