Abstract

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, T_c = 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).
