N2 - This experimental research was carried out to determine the ability of Al-doped lithium titanate (Li4Ti5O12, LTO) to function as an anode material synthesized by the facile sol-gel using lithium acetate (C2H3O2Li), titanium butoxide (C16H36O4Ti), and aluminum acetate (C4H7AlO5). All raw materials with Al contents of 1, 2, and 3 wt% were stoichiometrically dissolved in ethanol solutions using hydrochloric acid as a catalyst. After aging for 72 h, the precursors were sintered at 900°C for 2 h in air atmosphere. Furthermore, the effect of Al-doped on the crystal structure of LTO was studied using X-ray diffraction, while the morphology, size, and element of the sample were measured using scanning electron microscope (SEM). The cyclic voltammetry and capacity of the samples were investigated using the galvanostatic techniques in a half cell. The result of phase analysis showed the presence of LTO and rutile structures as impurities. In addition, the SEM images showed that the particle was in irregular form without porous observations. The average particle size of 6 mm was measured using image-J software, while the increase in dopant on the LTO structure led to the enhancement of the diffusion coefficient of Li-ion. Based on these characteristics, the spinel LTO provided an initial capacity of more than 100 mAhg-1 after charge-discharge at the rate of 0.1 C in range potential 0 - 3 V.
