Abstract: | SrLi2Ti6O14 has been prepared by using mesoporous TiO2 brookite as a template and reactant. The prepared particles retained the rounded shape of the precursor, leading to high dispersivity and high packing density. The material has been further electrochemically characterized in both half and full cells. It shows good cycling stability and rate capability. A 2.7-V cell has been built by combining a SrLi2Ti6O14 anode with a 4-V spinel cathode of LiMn2O4. This cell has a higher voltage compared to the 2.5-V LiMn2O4/Li4Ti5O12 system. |
