Primary Current Distribution in a Lead-Acid Battery Grid Electrode

Model ID: 9984


This 3D model example demonstrates the use of the Primary Current Distribution interface for modeling current distributions in electrochemical cells.

In primary current distribution, the potential losses due to electrode kinetics and mass transport are assumed to be negligible, and ohmic losses are govern the current distribution in the cell. Here you investigate primary current distribution in a positive lead-acid battery grid electrode during a high load (100 A) discharge.

In a traditional lead-acid electrode, the porous electrode is supported by a metal grid that also provides electronic conduction throughout the electrode. Optimizing the design of the grid leads to increased performance and lifetime as well as reduced weight.
