Abstract: Aspects of the disclosure involve a compliant pad for distributing force and/or pressure to a battery or battery pack. Whether a single electrochemical cell or pack of cells, force may be applied to maintain pressure on the cell or cells from proper operation. The compliant pad may be used to evenly distribute the force on or among the cells. In addition or alternatively, the compliant pad may include thermal properties to transfer heat to or from the cells, and between cells.

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: 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 of the disclosure involve a battery pack involving one or more stacks of battery cells, where the stacks of battery of cells are captured between plates or other members that are controlled to maintain force on the cells to manage the pressure on the cells in the stack. Some battery cells technologies, such as some forms of solid-state cells, optimally operate under a controlled stack pressure provided by the systems described herein.
