GEL POLYMER ELECTROLYTE AND CURRENT SOURCE USING IT

摘要

FIELD: electricity. ^ SUBSTANCE: gel polymer electrolyte includes polymer matrix obtained by means of interaction by grafting to copolymer of trifluorchloroethylene and vinylidene fluoride of copolymer of polyethylene glycol acrylate in organic solvent, at content of polyethylene glycol acrylate of 20-75%, where in grafted copolymer the content of links of vinylidene fluoride is 25-35%, with further introduction of lithium salt in amount of 5 to 20% in terms of 100 weight parts of matrix. ^ EFFECT: obtaining gel polymer electrolyte with high mechanical strength, stable structure of polymer and increased ionic conductivity; lithium current source has improved electric and operating characteristics. ^ 2 cl, 1 tbl
