$C/Li_{2}MnSiO_{4}$ as a composite cathode material for Li-ion batteries

This research concerns synthesis of C/Li2MnSiO4 nanocomposite materials and investigation of their structural and electrochemical properties. C/Li2MnSiO4 nanocomposites were produced in a one step process using sol-gel method. Primary carbon coatings of the active material grains were obtained from residual organic gel matrix. Morphology and properties of C/Li2MnSiO4 nanocomposite materials were investigated by thermal analysis (EGA-TGA/DTG/SDTA), X-ray diffraction (XRD), electrical conductivity measurements (EC), N2-BET adsorption measurements and transmission electron microscopy (TEM). The charge/discharge tests in electrochemical Li/Li+/(C/Li2MnSiO4) cells were carried out to characterize electrochemical behavior of the materials. Electrical conductivity measurements reveal very good conductivity of obtained composites (up to 0,36 S•cm-1) at room temperature (RT)
