Abstract:
Al, F-doped new perovskite lithium ion conductors Li3xLa 2/3-x□1/3-2x Ti1-yAlyO3-yF y(x=0.11) have been prepared by solid state reaction. It is found that a pure perovskite-structured phase with space group of P4mm(99) exits in the composition range of 0<y≤0.10. The sample with y=0.02 possesses the highest ionic conductivity of 1.06×10-3S/cm at room temperature, and its decomposing voltage is 2.3 V. The factors affecting the conductivity of this system are discussed.
