Template-assisted synthesis of high packing density SrLi2Ti6O14 for use as anode in 2.7-V lithium-ion battery

▶ This work deals with the preparation and characterization of an alternative anode material to graphite and lithium titanate, namely SrLi2Ti6O14. ▶ To reduce agglomeration issue related to the use of high temperature synthesis, the complex titanate has been prepared by using mesoporous TiO2 as template and reactant. The as prepared material displayed high purity, well defined particle shape (rounded) leading to high packing density material. ▶ Furthermore, the prepared material was combined with the spinel 4-V cathode leading to a 2.7-V lithium ion cell. The cell displayed high cycling stability and good rate capability which makes it a suitable candidate for high power applications.
