Synthesis and Characterization of Li_2Mn_x.Fe_(1-x)SiO_4 as a Cathode Material for Lithium-Ion Batteries

摘要

The synthesis, structure, and performance of carbon-containing Li_2Mn_xFe_(1-x)SiO_4 were studied in this work. A synthesis route has been developed for Li_2Mn_xFe_(1-x)SiO_4 materials, i.e., the carbon-containing Li_2Mn_xFe_(1-x)SiO_4 was synthesized by a solution route. The results of X-ray diffraction show that Li_2Mn_xFe_(1-x)SiO_4 solid solutions can be achieved in a wide compositional range. A. capacity of 214 mAh/g and energy density of 593 Wh/kg has been achieved for the Li_2Mn_xFe_(1-x)SiO_4 (x = 0.5) sample.
