Substitution of local TiO2 on the synthesis of Li4Ti5O12 for anodes lithium ion battery with solid state reaction method had been done. This study aimed to substitute raw materials TiO2 and determine the length of sintering time. Synthesis was done by mixing the raw materials like local TiO2 and LiOH.H2O in a stoichiometric then milled for 15 hours followed by calcination at a temperature of 600oC with sintering time of 2 hours for each samples. Sintering was done by varying the length of sintering time i.e. 4, 6 and 8 hours at a temperature of 850 °C. In this study the effect of sintering time on the material characteristics and performance of battery cells studied in detail. The characterization was conducted by the XRD to determine the structure and the LTO phases, SEM/EDX test to determine the morphology, surface topography and composition of all samples. PSA test was performed to determine the particle size while battery cell performance was tests with automatic charge-discharge battery cycler. From characterization found that the maximum length of time that is resistant to sintering samples 6 hours. The resulting active material has an LTO phase with spinel crystal structure simple cubic, but not produced a single phase, there are some impurity phases. The results of SEM/EDX provides irregular morphology, have pores, many impurities and varying sizes. Charge-discharge measurement showed that optimum sintering was got at 6 h which gave specific capacity about 50 mAh/g.
