Use the Electrode Current node to set the total current or average current density over an external electrode or porous electrode boundary — typically at the interface between the electrode and the current collector or current feeder. The condition sets the total inward current without imposing the current density distribution. The potential along the boundary is calculated in order to satisfy the total value of the current.
In the Lithium-Ion Battery and the Battery with Binary Electrolyte interfaces, if the Define cell state of charge (SOC) and initial charge inventory checkbox has been ticked in the Cell Settings section on the physics interface top node, the
Total current can be specified either explicitly or as a multiple of the C-rate current variable (xxx.I_1C_cell, where xxx is the physics interface tag) that is defined by the global
SOC and Initial Charge Distribution node.
When using the Total current option in 1D or 2D, the boundary area is based either on the
Cross-sectional area (1D), or the
Out-of-Plane thickness (2D) properties, set on the physics interface top node.
