Pressure sensitive adhesive electrolyte

A pressure sensitive adhesive polymer electrolyte having a peel adhesion by test A of more than 1 N/cm and an ionic conductivity by test B of more than 10−6 (ohm*cm)−1, prepared by polymerizing:5-60 wt % of acrylate monomer from the group of the (meth)acrylic esters having 4-15 carbon atoms, which as a homopolymer would have a Tg by test C of less than −30° C.,10-80 wt % of acrylate monomer from the group of the (meth)acrylic esters having 4-25 carbon atoms and containing at least one heteroatom, which as a homopolymer would have a Tg by test C of less than 100° C.,0.05-10 wt % of initiator,2-13 wt % of conducting salt,optionally plasticizer,and optionally solvent, which after the polymerization is typically removed at least partly,where optionally one or more of the components are added at least proportionally only during or after the polymerization.
