The aid of the work - synthesizing boron-containing salt components containing lithium cations using microwave method with determination influence of the synthesis regime upon phisic-chemical and electrochemical properties of the salts obtained. Estimation the influence of the nature of initial components for synthesis, composition of precursor and method of its preparation on phisic-chemical and electrochemical characteristics of lithiated oxide materials synthesized by microwave method. Estimation the influence of the microwave irradiation power and regime, elaboration the cells for synthesis. Results of the review on literature data concerning application of the microwave irradiation in the chemical synthesis of organic and inorganic compounds confirmed its availability in preparation of electrode materials and ion-containing components of electrolytes for lithium-ion batteries of wide spectrum of application in modern technique, electronics, etc. Interaction of the microwave irradiation with reactants enables preparation of high quality products, at the same time shorting the synthesis duration compared to traditional methods. By the methods of thermogravimetric, X-ray and electronic microscopy analysis the structure characteristics of lithium-manganese spinel LiхMn2O4 (х = 1.05-1.35) obtained using microwave irradiation have been determined. The effective method of simplified preparation of the mixture from initial components using ultrasonic dispersing in aqueous medium has been proposed. Samples of lithium bis(oxalate)borate have been synthesized using microwave irradiation of different intensity, and diapasons of the electrochemical stability potentials of the electrolyte solutions based on the compounds obtained have been determined.
