| Description | Journal: Iop Conference Series: Materials Science and Engineering $Li_{4}Ti_{5}O_{12}$ (LTO) is one of the material that has the potential as anode in lithium ion battery that is safe to use and has a long life cycle. In this research, LTO was synthesed by sol-gel method using oxalic acid as chelating material, it is expected to produce materials with smaller particles and homogeneous distribution. The LTO sol-gel compared to commercial LTO. Characterization was carried out by X-ray diffraction (XRD), scanning electron microscopy (SEM), electrochemical impedance spectroscopy (EIS). The measurement of LTO battery performance is carried out by charge discharge and electron impedance spectroscopy. The sol-gel LTO has a purity of 99%, which is higher than 57% commercial LTO. The average particle size is 1 μm, and the conductivity is $7.6x10^{−7}$ $S.cm^{−1}$. While commercial LTO has a purity of 57%, the average particle size is 30 μm and conductivity is $7.4x10^{−7}$ $S.cm^{−1}$. Batteries with synthesized LTO anodes have a capacity of 25.9% higher in the first cycle and 110% higher in fifth cycles incomparison with batteries used commercial LTO anodes. |
