Abstract: Electrochemical systems for mitigating or reducing the release of undesirable by-products of electrochemical cells are provided. These systems may be particularly relevant to the sequestering of hydrogen sulfide gas in solid state electrochemical cells with sulfide-based electrolytes. Some of the systems include an integrated hydrogen sulfide eliminating layer or microspheres containing a hydrogen sulfide eliminating material adjacent to one or more electrochemical cells and within a containment structure.

Abstract: A traction battery includes a plurality of solid-state-battery cells arranged in a stack, a pair of endplates engaging with opposing ends of the stack and configured to generate a predetermined magnitude of stack pressure in the stack, and a plate of shape-memory alloy disposed in the stack. The plate of shape-memory alloy is configured to expand or contract in thickness responsive to volume changes within the battery cells to maintain the stack pressure within a range of the predetermined magnitude.
