Abstract

Electrochemical cells employing liquefied gas electrolytes may experience degradation of certain polymer components, such as tapes made from poly(ethylene terephthalate), poly(butylene terephthalate), or polydimethylsiloxane. These materials exhibit low chemical stability, potentially leading to cell failure. Embodiments disclosed herein utilize stable polymers, including polyimide, polypropylene, or polyethylene as tape carriers and poly(methyl methacrylate) as adhesives, to enhance compatibility and performance in such cells.
