Abstract: Methods clad battery cells and comprise adhesively bonding at least one crosslinkable adhesive layer of a adhesive film and the at least one bottom side of a battery cell, adhesively bonding the at least one crosslinkable adhesive layer of the adhesive film and at least two first side walls of the battery cell, adhesively bonding the at least one crosslinkable adhesive layer of the adhessive film and at least two second side walls of the battery cell, and adhesively bonding the at least one crosslinkable adhesive layer of the adhesive film and at least one top side of the battery cell, wherein the methods further comprise at least partly crosslinking the crosslinkable adhesive layer.

Abstract: The invention relates to 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), wherein the middle layer (2.2) comprises a porous electrically nonconductive structure, and wherein a layer of a polymer-based electrolyte (2.1, 2.3) is arranged on both opposite sides of the porous electrically nonconductive structure, wherein at least one of the superposed layers (2.1, 2.2, 2.3) contains a ceramic material, wherein the ceramic material of the middle layer (2.2) 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) (2.1, 2.3) is a metal ion-conductive ceramic material.
