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.

Abstract: A process for preparing a solid electrolyte that includes mixing a lithium source with a sulfur source and a compound containing phosphorous and sulfur to form a composite, then heating the composite to the melting point of the compound containing phosphorous and sulfur to form the solid electrolyte material. A solid electrolyte material prepared by the process, wherein the solid electrolyte material is of formula I, which is Li(7−y−z)PS(6−y−z)X(y)W(z) wherein X and W are individually selected from F, Cl, Br, and I; where y and z each individually range from 0 to 2; and where y+z ranges from 0 to 2.
