The review contains information on modern methods and approaches to the obtaining of solid lithium-accumulating compounds of various classes, their modification with the purpose of increasing the properties of accumulation of lithium ions in the structure, accelerating the kinetics of reversible lithium insertion, the formation of electroactive composites based on these compounds, composite electrode layers on a metal substrate using these composites.

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.

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.
