Abstract: Methods, stacks and electrochemical cells are provided, in which the cell separator is surface-treated prior to attachment to the electrode(s) to form binding sites on the cell separator and enhance binding thereof to the electrode(s), e.g., electrostatically. The cell separator(s) may be attached to the electrode(s) by cold press lamination, wherein the created binding sites are configured to stabilize the cold press lamination electrostatically—forming flexible and durable electrode stacks. Electrode slurry may be deposited on a sacrificial film and then attached to current collector films, avoiding unwanted interactions between materials and in particular solvents involved in the respective slurries. Dried electrode slurry layers may be pressed or calendared against each other to yield thinner, smother and more controllably porous electrodes, as well as higher throughput. The produced stacks may be used in electrochemical cells and in any other type of energy storage device.

Abstract: A laminated rechargeable element includes a jacket and an electrode assembly. The electrode assembly is accommodated in the jacket together with an electrolyte, and includes a separator, a sheet-shaped positive electrode and a sheet-shaped negative electrode. The electrode assembly is formed by laminating the positive electrode and the negative electrode with the separator interposed between the positive electrode and the negative electrode. The separator includes an ion-permeable substrate and ion-permeable bonding layers formed on a top surface and a bottom surface of the substrate. The positive electrode and the negative electrode are welded to respective bonding layers of the separator. The jacket is formed of two flat, rectangular stainless steel laminate films welding together at their peripheries, and is welded to the electrode assembly.
