Abstract

Lithium titanate, Li4Ti5O12, has been synthesized by the Pechini process, citrate route, and EDTA-citrate route at various final annealing temperatures. The materials obtained have been characterized by scanning electron microscopy, X-ray diffraction, impedance spectroscopy, and thermogravimetry in combination with mass spectrometry of gaseous products. The samples prepared by the Pechini process and annealed at 1073 K had the lowest ionic conductivity. The highest ionic conductivity was offered by the materials prepared at 673 K.
