%X Li4Ti5O12 nanoarrays were prepared with sol―filling template method. The morphology and structure of Li4Ti5O12 nanoarrays were characterized by SEM, EDS and XRD. The experimental results show that spinel Li4Ti5O12 nanoarrays with average diameter of 70nm are obtained by repeating the following steps for four times: immersing the porous AAO in sol of 0.8mol/L under ―0.1MPa and drying at 80  , then roasting at 900   for 20h in the air. The diameter and length of Li4Ti5O12 nanoarrays are controlled by diameter, thickness, sol concentration and filling times, with the crystalline structure rested on the roasting time and temperature. On the basis of characterization for nanoarrays, a possible formation mechanism is supposed.
