Parameters of lithium cation intercalation /deintercalation processes in the solid phase of modified electrodes. The work aim of this stage is to modify the electrode materials of anodes and cathodes of lithium current sources. Study of the parameters of intercalation / deintercalation processes of lithium cations in the solid phase of modified electrodes. Research in a wide temperature range of conductivity of modified solid electrolytes.Methods of investigations - electromagnetic non-contact method of measuring the materials conductivity, electrochemical methods: impedance spectroscopy, cycling in galvanostatic mode, and cyclic voltammetry. The dependence of the intercalation capabilities of sulfur-based composites on the nature of the carbon additive was investigated. The electrochemical properties of MnO2 electrodes modified with an organic semiconductor, melanin, at an elevated temperature have been established. The dependence of the conductivity of solid electrolytes based on inorganic and organic materials on the nature of the components included in their composition is shown. Conductivity and magnetic properties of carbon powder materials of various nature were determined by non-destructive non-contact electromagnetic method. The obtained results make it possible to justify the choice of carbon material as anodes and components of cathode materials in lithium-ion current sources; Field of application C 27.20 Manufacture of batteries and accumulators.
