FIELD: electrical industry.
SUBSTANCE: invention relates to electrical engineering and can be used for production of lithium-ion batteries. Gel electrolyte consists of a polymer matrix, an organic solvent and a lithium salt. Polyurethane film material acts as matrix material, to obtain which polyoxypropylene glycol with molecular weight of 1,000, triethanolamine, orthophosphoric acid, succinic anhydride, hexamethylene diisocyanate, dibutyltin dilaurate and acetone are used.
EFFECT: high specific ionic conductivity, lithium cation transfer numbers of the gel electrolyte and its ability to operate in an accumulator with a lithium anode and an organic cathode for a large number of charge-discharge cycles.
