Изобретение относится к области твердотельных полимерных ионных проводников, а именно - к литийпроводящим электролитам, который может быть использован в литиевых перезаряжаемых батареях, электрохимических устройствах и сенсорах. Авторами предлагается твердый литийпроводящий электролит, содержащий полимерную матрицу на основе полиакрилонитрила и неорганическую ионогенную соль лития, отличающийся тем, что он содержит в качестве полимерной матрицы сополимер полиакрилонитрила, в котором в качестве компонентов сополимеризации содержатся акрилатные, либо метакрилатные звенья, а также звенья карбоновых кислот, при следующих соотношениях компонентов, мол.%: сополимер полиакрилонитрила 83.3-66.7, ионогенная неорганическая соль лития 16.7-33.3, а также способ получения твердого литийпроводящего электролита, включающий растворение полимера и неорганической соли лития, получение смеси их растворов, помещение смеси на подложку из политетрафторэтилена и последующую термообработку при пониженном давлении, отличающийся тем, что термообработку проводят в три стадии, а именно: I стадия - при температуре 0-25°С и давлении 1.103-4.103 Па; II стадия - при температуре 0-25°С и давлении 1-14 Па; III стадия - при температуре 45-70°С и давлении 1-14 Па. Предлагаемый электролит позволяет получить высокие стабильные значения электропроводности не хуже 10- 4 Ом- 1 см- 1 при комнатной температуре.The invention relates to the field of solid polymer ionic conductors, namely, to lithium-conducting electrolytes, which can be used in lithium rechargeable batteries, electrochemical devices and sensors. The authors propose a solid lithium-conducting electrolyte containing a polyacrylonitrile-based polymer matrix and an inorganic ionic lithium salt, characterized in that it contains a polyacrylonitrile copolymer as a polymer matrix, at the following ratios of components, mol.%: polyacrylonitrile copolymer 83.3-66.7, ionic inorganic lithium salt 16.7-33.3, as well as a method for producing a solid lithium-conducting electrolyte, including dissolving a polymer and an inorganic lithium salt, obtaining a mixture of their solutions, placing the mixture on a polytetrafluoroethylene substrate and subsequent heat treatment under reduced pressure, characterized in that the heat treatment is carried out in three stages, namely: I stage - at a temperature of 0- 25 ° C and a pressure of 1.10 3 -4.10 3 Pa; Stage II - at a temperature of 0-25 ° C and a pressure of 1-14 Pa; Stage III - at a temperature of 45-70 ° C and a pressure of 1-14 Pa. The proposed electrolyte allows to obtain high stable values of electrical conductivity no worse than 10 - 4 Ohms - 1 cm - 1 at room temperature.
