| 제목 | Boron-doped Li4Ti5O12 as an anode material for lithium ion batteries with high rate capabilities and long-term cyclability |
| 초록 | Li4Ti5O12 (LTO) is expected as the most promising anode materials for lithium ion batteries (LIBs) because of several unique advantages such as zero-strain during charging-discharging, long-term cycling stability, good high-rate performance, and a wide voltage plateau around 1.55 V with enhanced safety. Simultaneously, the LTO has a several disadvantage such as poor electronic and Li ionic conductivities, resulting in low performance at high current rates. To overcome the drawbacks, a doping method has been proposed to improve the electrochemical performance. In this work, doping with appropriate elemented such as boron improves the electronic conductivity of LTO. Boron-doped LTOs with various contents (0, 5, 10, 20 at %) were synthesized via a sol-gel method. These materials as anode materials for LIBs were evaluated through a variety of physical and chemical characterization techniques. |
