Lithium-Ion Battery, Deformed Geometry Model Wizard Entry
The Lithium-Ion Battery, Deformed Geometry () Model Wizard entry is a predefined multiphysics interface for time-dependent modeling of deformations that occur as a result of a deposition/dissolution processes in a lithium-ion battery, for instance lithium metal dissolution at the negative electrode of a lithium-metal battery.
By choosing the multiphysics interface, a Lithium-Ion Battery Interface interface and a preset instance of a Deformed Geometry are added to the component. Deforming Electrode Surface and Nondeforming Boundary multiphysics coupling nodes that couple electrode reactions to boundary velocities are also added by default. The predefined couplings are set up so that the deforming geometry velocity is set to the total depositing velocity on boundaries where deposition/dissolution processes occur, and zero on all other boundaries.
Note that is also possible to extend an already existing current distribution model to include electrode deformations by manually adding a Deformed Geometry interface and the required Multiphysics coupling nodes.
