FIELD: electricity.
SUBSTANCE: proposed solid polymer electrolyte comprises a polymer matrix filled with a solution of lithium salt in an ion liquid (15.0-43.8 wt parts). The polymer matrix is a semi-mutually penetrating net comprising a linear elastomer - butadiene-acrylonitrile rubber (BANR) (8.8-14.5 wt parts) and a cross-linked ion copolymer (35.0-58.1 wt parts), produced from monomers selected from groups of (meth)acrylates of polyethylene glycol (MPEG), di(meth)acrylates of polyethylene glycol (DMPEG) and (meth)acrylate ion liquids (MIL), at the ratio of MPEG:DMPEG:MIL 1:2:6 (wt). The most efficiently the solid polymer electrolyte may be used as a separator in thin-film lithium-ion sources of current.
EFFECT: improved properties.
