| 中文摘要 | We have reported a facile method to fabricate hierarchical boron-doped rutile submicrosphere TiO2 (SMT), whose primary particles are similar to 20 nm in diameter. The as-synthesized boron-doped SMT shows excellent cycling performance and rate capability in comparison with undoped TiO2 as an anode material in Lithium-Ion Batteries (LIBs). It has a very stable capacity of similar to 190 mA h g(-1) for 500 cycles at 1C. In addition, the density functional theory (DFT) calculations are carried out to indicate that a low concentration (<1.0 at%) of boron doping could enhance the carrier mobility mu and electrical conductivity sigma, and thus reveal the relationship between the electronic structure of boron-doped SMT and the performances of the boron-doped SMT anode in LIBs. Our results also clearly demonstrate the importance and advantage of the hierarchical submicrometer-sized spherical morphology of the TiO2 anode in LIBs. |
