FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering and can be used in production of lithium primary and secondary power sources, as well as super capacitors. Gel polymer electrolyte contains polymer matrix, organic solvent and inorganic ionogenic lithium salt, at that, polymer matrix is polysulphone and perfluorodiphenylol propane with average molecular weight (0.5-1.0)·105 copolymer at following weight ratio of components of electrolyte, weight parts: polysulphone and perfluorodiphenylol propane copolymer - 100, Ionic inorganic lithium salt - 6-28, organic solvent - 80-140.
EFFECT: technical result is higher specific electric conductivity gel polymer electrolyte, provision of its chemical and electrochemical stability, as well as high homogeneity of electrolyte and increase of lithium diffusion coefficient.
