Abstract

Li4Mn5O12 material has been successfully synthesized by hydrothermal method. Synthesis conditions are: Li:Mn molar ratio 5:3, temperature at 120oC, 216 hours, calcinating at 500oC for 6 hours. The obtained material was analysed its components, characterized by X-ray diffraction (XRD), flame atomic adsorption spectrometry (F-AAS), Fourier transform infrared spectroscopy (FT-IR), Total Carbon (TC), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Cyclic Voltammetry technique (CV). The obtained Li4Mn5O12 material has spinel structure (Fd3m), crystal size in 40-60 nm, Li:Mn ratio ~ 0,798, average valence of Mn in product is 3.98 ± 0.02. Li-ions can reversibly insert-extract in Li4Mn5O12 material in well.
