Gas-induced bulging in pouch-cell batteries: a mechanical model
Andrea Giudici, Colin Please, Jon Chapman
Over the long timescale of many charge/discharge cycles, gas formation can result in large bulging deformations of a Lithium-ion pouch cell, which is a key failure mechanism in bat…

Mechanical stresses in pouch cells: a reduced order model
Andrea Giudici, Jon Chapman, Colin Please
In a pouch cell battery, the intercalation of lithium ions into the active particles means the electrodes want to expand. However, since the electrodes are attached to stiff curren…
