Series Of Experiments

A series of experiments were conducted to study the thermal failure hazard of large-format commercial lithium-ion batteries with typical states of charge in a calorimeter apparatus. The results indicate that the thermal failure penetration of the lithium-ion battery with 70% state of charge is faster than the lithium-ion battery with 50% state of charge. Two typical thermal failure modes, “Gas-driven mode” and “Flame-driven mode,” were also observed, corresponding to lithium-ion battery with 70% state of charge and 50% state of charge, respectively. Significant heat release, accompanied by large amount of carbon dioxide (CO2) release, took place for lithium-ion battery with 50% state of charge. Inversely, lithium-ion battery with 70% state of charge presented a lower heat release while more carbon monoxide (CO) generation and obvious mass loss trend. This study may serve as a reference for safe storage, application, and transportation in lithium-ion batteries.

Lithium Hexafluorophosphate

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 (LiPF6/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℃ soaking conditions. The soaking condition significantly influences heat-seal strength, especially for the packages heat-sealed at low temperatures and short heat-sealing times. Higher storage temperature during electrolyte-soaking accelerates the heat-seal strength decrease. Failure modes are affected by the soaking conditions and become more complicated than the packages without soaking. The optimized heat-sealing processing window is obtained under a certain soaking condition. The electrolyte hydrogen ion concentration (pH) decreases with longer soaking time and higher storage temperature, indicating that acidification may also contribute to decreased heat-seal strength. The results are important for understanding how stored lithium-ion batteries deteriorate and can help to guide battery design to maximize their shelf life.
