The purpose of the work is the development of the magnesium based negative electrode and optimization of the non-aqueous electrolyte composition based on magnesium salts. Investigation of the electrochemical properties of the negative electrode in non-aqueous electrolytes. Development of the block diagram of the information-measuring system of correlation of the magnesium power source parameters and the operational parameters of the innovative devices. Methods of research are impedance spectroscopy, galvanostatic discharge, cyclic voltammetry; electromagnetic non-destructive noncontact method for determining the electrical conductivity of electrode powder components, X-ray diffraction (XRD). The laboratory technology of production the magnesium based negative electrode is developed. The electrochemical processes, which took place on magnesium electrodes in non-aqueous electrolytes, were investigated by methods of galvanostatic discharge and impedance. The composition of non-aqueous electrolyte was optimized. The ionic conductivity of electrolytes in the range of temperatures from -20 to +70 °C was determined, electrochemical stability of those in contact with electrode materials was investigated. The electronic conductivity of powdered components of electrode materials is measured. The block diagram of the information-measuring system of the correlation of the magnesium power source and the operational parameters of the innovative devices is developed. Area of use: C 27.20 Manufacture of batteries and accumulators.
