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. The influence of solid-phase synthesis conditions on the electrochemical characteristics of the cathode material was determind. Electrochemical characterization was studied by the method of direct current chronopotentiometry (galvanostatic charge-discharge).
