Abstract
An electrochemical stack assembly includes a laminated pouch surrounding a frame which encloses solid-state electrochemical cells and electrochemical stacks. In some embodiments, an electrochemical stack assembly includes one or more electrochemical cells, each electrochemical cell comprising a solid-state electrolyte to form at least one electrochemical stack with two major surfaces and four minor surfaces; a frame surrounding the at least one electrochemical stack with space between the frame and each of the four minor surfaces; and a laminated pouch surrounding the frame and the at least one electrochemical stack, the laminated pouch in contact with one or both of the major surfaces. In some embodiments, the frame comprises a tray. In some embodiments, the electrochemical stack assembly comprises two trays, each with an electrochemical stack comprising an electrochemical cell, the cell comprising a solid-state electrolyte.
