Abstract: Aspects of the present disclosure involve utilizing layers, such as an outer carrier foil layer, that provide a surface energy sufficient to prevent separation of the layers of the stack during lamination while allowing for the proper densification of the solid-electrolyte separator layer. In one particular example, a Corona-treated or carbon coated outer foil layer may be used during manufacturing of the electrode stack that provides a sufficient surface energy to adhere to the solid-electrolyte separator layer during the lamination process, while allowing for subsequent peeling of the Corona-treated outer foil from the electrode stack after densification without damaging the remaining layers of the stack. The electrode laminate discussed herein may be utilized in any type of battery or electrochemical cell, including solid, semi-solid, or liquid-based batteries.

Abstract: Aspects involve systems and methods for producing an electrode laminate for a battery that includes a stack of a center electrode layer, a solid-state electrolyte (SSE) layer, and carrier film layer (such as an aluminum foil layer), which is removed prior to use in a cell. To laminate the lithium foil layer to the SSE layers, the stack may be fed through a calender press device comprising a first roller and a second roller. The rollers exert a compressive force on the stack to laminate the layers together while also reducing the porosity of the materials within the stack (densifying), enhancing material contact, causing some layers to adhere or otherwise laminate, and/or also causing some layers to partially separate. The pressure applied to the stack by the calender press may correlate to a spacing between the first roller and the second roller, which may be adjustable by a controller.

Abstract: A peeling device for manufacturing of an electrode stack includes an upper wedge and a lower wedge between which the electrode stack is fed after a calendering process. A respective lifting roller may be located at the output ends of each of the wedges, which through coordinated action peels the aluminum layers away from the corresponding layer of the electrode stack. The peeling force, exerted by rollers capturing upper and lower aluminum foil sheets of the stack, may be controlled and relatively uniform, thereby enhancing the ability to peel the foil from the stack while not damaging the relatively delicate remaining layers. The aluminum foil is directed away from the stack along an outer planar surface of the respective wedge where the foil can then be wound around the respective rollers.
