This node is available for the Two electrodes model option. The settings of this node define the host capacity loss that occurs in the positive electrode of the battery due to parasitic reactions on the positive electrode.
The Loss kinetics, positive can be specified by either using a
Built in expression or an
User defined expression, with respective inputs for the positive electrode. The
Built in option calculates a positive loss current based on a
Calendar aging time constant that defines the rate of the parasitic reactions on the negative electrode, and dimensionless aging factors dependent on
Voltage,
Current,
Aging history, and
Temperature, respectively. All the settings in this node are similar to those described in the
Capacity Loss node, except that enabling
Voltage specifies the
Loss potential (instead of the
Offset potential). The
User defined option of
Loss kinetics, positive can be used to explicitly specify the
Loss current, positive.
