Abstract
A lithium titanate doped with a barium oxide and a manufacturing method thereof are provided. At first, a barium source material, a lithium source material and a titanium source material are mixed together to prepare a mixture. Then, a drying process is applied to the mixture. Thereafter, a sintering process is applied to the mixture after the drying process, thereby obtaining the lithium titanate doped with the barium oxide. The lithium titanate doped with the barium oxide has the following chemical formula: BaxLi4Ti5O12+x, wherein 0.006≦x≦0.12. A lithium ion battery is also provided, which has an excellent cycling stability, a fast charge-discharge capability and a high safety performance.
