Synthesis and properties of Li-Ti-O spinel (LiTi2O4)
A simple method for preparing LiTi2O4 is reported in this paper. Characterization by the X-ray diffraction method indicated that the LiTi2O4 had formed with the spinel crystal structure. The particle size and shape of the compound were observed by scanning electron microscopy techniques. The superconducting and electrochemical properties of LiTi2O4 spinel have also been investigated. The results showed that this material is not only a superconductor with critical temperature, Tc = 13 K, but also a promising anode material, which showed discharge specific capacity (240 mAh g−1) and excellent cycling ability in the range of 3.00–0.01 V at certain current density (20 mA/g).
