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.
