Battery open-circuit voltage is not purely chemical
Andrea Giudici, Christoph Pohl, Alberto Salvadori +3
Open-circuit-voltage (OCV) curves are commonly treated as intrinsic chemical properties of electrode materials. However, this view is incomplete. In ion-insertion batteries, OCV al…
Incorporating multiscale mechanics in lithium-ion battery models
Andrea Giudici, Andres F. Galvis, Smita Sahu +4
Lithiation-induced swelling in lithium-ion batteries generates stresses not only within active particles, but also across the surrounding non-active matrix, electrodes, and cell st…
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…
