N2 - The surface of Li4Al0.03Ti4.97O12 was successfully modified using carbon from sugar. Li4Al0.03Ti4.97O12 samples were obtained via sol-gel route through the sintering of 850°C for 4 hours at room atmosphere. While the modifying process using sugar as carbon sources was conducted by pyrolysis process at 600°C for 2 hours under N2 atmosphere. Removing carbon process from Li4Al0.03Ti4.97O12 was done by sintering again at 600°C for 2 hours under air atmosphere. There are three samples, pure, carbon-modified, and carbon-removed of Li4Al0.03Ti4.97O12, prepared in this report. Characterizations were conducted using XRD, FESEM, EIS, CV and CD to know the phases, morphology, conductivity, electrochemistry, and specific capacity, respectively. XRD patterns confirmed the spinel structure of Li4Al0.03Ti4.97O12 and rutile as impurity phase. There are not any Al phases indicated that Al ion enters the spinel. Carbon-modified significantly changed the morphology of sample. However, carbon from sugar decrease the ionic diffusion, specific capacity, and power density. The highest specific capacity achieved by pure Li4Al0.03Ti4.97O12 can reach of 150 mAh/g and it can be discharge until 10 C.
