摘要：As a popular anode material for lithium-ion batteries,anatase TiO2 nanoparticles with exposed{001}facets usually exhibit exceptional lithium storage performance owing to more accessible sites and fast migration of lithium ions along the good crystalline ***,there are few researches on the lithium storage capability of TiO2 nanocrystals with other high-energy facets owing to lack of effective synthesis method for controlling crystal ***,anatase TiO2 nanocrystals with exposed{010}-and[111]-facets are successfully prepared by using the delaminated tetratitanate nanoribbons as *** electrochemical properties of these TiO2 nanocrystals with high-energy surfaces and the comparison with commercial TiO2 nanoparticles(P25)are *** is found that the cycle and rate performance of TiO2 nanocrystals is highly improved by reducing the particle size of ***,TiO2 nanocrystals with exposed{010}-and[111]-facets exhibit better lithium storage capacities in comparison with P25 without a specific facet though P25 has smaller particle size than these TiO2 nanocrystals,indicating that the exposed facets of TiO2 nanocrystals have an important impact on their lithium storage ***,the synthesis design of high-performance TiO2 materials applied in the next-generation secondary batteries should both consider the particle size and the exposed facets of nanocrystals.
