Synthesis and Electrochemical Properties of Lithium-Accumulating Electrode Material Based on Li?MnSiO?

Synthesis of electrode material based on Li2MnSiO4/С using widely used, environmentally safe and inexpensive Li, Si and Mn-containing precursors was considered. Mechanochemical activation was used for improving the flow of thesolid-state synthetic process and providing the necessary reactivity to obtain the target product with a high content of the main lithium-accumulating compound.Structural and morphological features of the composite were investigated by X-ray diffraction, laser diffraction granulometry.

Peculiarities of Obtaining and Electrochemical Properties of Lithium-Ion Battery Cathode Materials Based on Iron(II)-Lithium Orthosilicate

Various strategies for the synthesis of promising electrode materials for lithium-ion battery (LIB) based on iron(II)-lithium orthosilicate (Li2FeSiO4) using widely distributed, environmentally friendly and inexpensive starting materials are considered. The materials obtained are multicomponent electroactive composites that include, in addition to the main lithium accumulating component, also auxiliary structure-forming and electrically conductive components based on the products of the pyrolytic decomposition of organic compounds.
