MULTI-LAYER ELECTROLYTE ASSEMBLY FOR LITHIUM BATTERIES

The invention relates to an electrolyte arrangement for a cell having at least one anode () and at least one cathode () comprising at least three superposed layers (), wherein the middle layer () comprises a porous electrically nonconductive structure, and wherein a layer of a polymer-based electrolyte () is arranged on both opposite sides of the porous electrically nonconductive structure, wherein at least one of the superposed layers ( ) contains a ceramic material, wherein the ceramic material of the middle layer () is selected from metal ion-conductive ceramic material, a ceramic material which does not conduct metal ions, and/or mixtures thereof, and the ceramic material of the polymer-based electrolyte layer(s) () is a metal ion-conductive ceramic material.
