AMP20 Cell Thickness Expansion
During the regular cycling that a cell experiences from 100% SOC to 0% and back, the cells will expand
approximately 1% their initial thickness. Over the course of the cell’s lifetime as it ages during regular service, its
thickness will grow to be 3 – 5% greater than initial thickness.
The graphs in Figure 8 show how much the cells can expand over the course of a charge and discharge cycle.
