modelGraphite
Graphite phase
Extends from Icons.Phases.Solid (Icon for a solid phase), PartialPhase (Base model for a phase).
Information
From a physical standpoint, the electrolytic double layer is probably best considered its own phase, but it is modeled as a part of the graphite phase in order to reduce the number of connections. It is assumed to store no material, translational momentum, or thermal energy. It only stores electrical energy due to a charge difference.
C+ and e- are assumed to have the same temperature. C+ should be used to initialize the temperature.
See Species.'e-'.Graphite.Fixed for assumptions. For more information, please see the PartialPhase model.
