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.
