1. An electrolyte arrangement for a cell having at least one anode (1) and at least one cathode (3) comprising at least three superposed layers (2.1, 2.2, 2.3), said at least three superposed layers having:
a middle layer (2.2) comprised of a porous electrically nonconductive structure, and
a layer of a polymer-based electrolyte (2.1, 2.3) arranged on both opposite sides of the porous electrically nonconductive structure,
wherein only one of the polymer-based electrolyte layers (2.1, 2.3) contains a lithium ion-conductive ceramic material, and
wherein the middle layer (2.2) is ceramic-free, and
wherein the polymer-based electrolyte layers comprise a polymer selected from the group consisting of polyethylene oxide, polypropylene carbonate, polyethylene carbonate, poly (bis((methoxyethoxy) ethoxy) phosphazene), polypropylene oxide, polysiloxane having an average molecular weight of from 300 g/mol to 10,000 g/mol and mixtures and copolymers thereof and an organic or inorganic salt of lithium.
