The new method of lithium bis-oxalatoborate salt synthesis with the use of microwave irradiation of the solid-phase mixture has been developed. The main physic-chemical characteristics of the synthesized salt in the most part of aprotonic solvents have been investigated. Phase diagrams of LiAnion - tetraglime systems have been investigated where Anion is bis-oxalatoborate, bis-trifluoromethylsulfonimide. These systems have been shown to keep liquid state in wide temperature range, and to be able to glass forming. Dependence of the thermal stability of salt-solvate systems tetraglime - lithium salt on the lithium salt anion nature has been determined. Influence of lithium salts concentration and nature upon electrochemical stability of salt-solvate electrolytes glime solvent - lithium salt has been estimated. Electrochemical properties of cathodes based on titanium dioxide, lithiated vanadium oxide, manganese spinel, and fluorocarbon have been studied depending on the electrolyte composition, current density, and temperature. Testing of the lithium-ion battery development samples has been fulfilled and the electrolyte composition effect upon their main electrochemical characteristics has been determined.
