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

This research concerns synthesis of $C/Li_{2}MnSiO_{4}$nanocomposite materials and investigation of their structural and electrochemical properties. $C/Li_{2}MnSiO_{4}$ 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 $C/Li_{2}MnSiO_{4}$ 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/$Li^{+}$/($C/Li_{2}MnSiO_{4}$) 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$\cdot cm^{-1}$) at room temperature (RT).
