Part of Cell degradation and Cell capacity fade.

One of the Reasons for atypical cell degradation.

Related:

• Time, not cycle count is the dominant factor of SEI thickening
• SEI thickness grows as the square root of the calendar age of the cell
• Lithium deposition overtakes the SEI growth as the leading capacity fade mechanism at 1C rate and 25 °C
• We could roughly discern between the physical causes of cell degradation from the SoH, the pace of degradation, and the average cell temperature and current over the battery lifetime
