| 中文摘要 | Intrinsic structure stability of Li(4)Ti(5)O(12), Li(2)TiO(3) and Li(2)Ti(3)O(7) is confirmed by XRD in the broad electrochemical range (0.0-5.0V versus Li/Li(+)). It is clearly that all the Li-Ti-O ternary compounds can accommodate lithium ions in their crystal structures. Attributed to the stable framework all these Li-Ti-O, compounds show excellent cycle calendar life. One drawback to date for these compounds is the poor kinetic behaviors result from low electronic conductivity. Carbon coating is a kind of effective method for improvement. Comparing with carbon free Li-Ti-O ternary compounds, it is obvious that thermal stability, cyclability and reversible specific capacity are obviously enhanced with carbon coating. After many cycles, large reversible capacities approximate 224 mAh g(-1) (50 cycles), 90 mAh g(-1) (50 cycles) and 219 mAh g(-1) (27 cycles) are delivered for Li(4)Ti(5)O(12)/C, Li(2)TiO(3)/C and Li(2)Ti(3)O(7)/C, respectively.
