Influence of lithium hexafluorophosphate/ethylene carbonate/dimethyl carbonate electrolyte soaking on heat seal strength of polyamide 6/aluminum/cast-polypropylene laminates used as lithium-ion battery packaging

Abstract

The heat-seal strength of polymer-metal-polymer laminates, widely used in the packaging industry and more recently for pouch lithium-ion batteries, is a critical factor for the integrity of flexible package structures during service. The influences of lithium hexafluorophosphate/ethylene carbonate/dimethyl carbonate (LiPF 6 /EC/ DMC) electrolyte soaking time and storage temperature on heat-seal strength were investigated through T-peel testing using a universal testing machine. Sealed multilayer laminates' heat-seal strength and their failure modes were measured for specimens sealed at various heat-sealing temperatures and dwell times before and after exposure to room temperature and 60 C soaking conditions. The soaking

A review of high performance polymer nanocomposites for packaging applications in electronics and food industries

“…3,4 For example, nanocomposites based on polyamide, epoxy, polyethylene, and other matrices have been employed in battery packaging. 5 The packaging materials based on appropriate matrix and nanofiller endowed optimum mechanical properties and biological features, along with the necessary barrier properties against gases and water vapor during storage and handling. Efficient nanocomposite packing materials must have high durability and, preferably, rapid biodegradability, so that they will not cause environmental challenges.…”
