The battery tolerated only minor defects without the triggering of lithium plating. Due to the symmetry, the defect size (0.5 mm) in the model was equivalent to a defect width of 1 mm in an actual battery, in which case lithium plating still occurred. A 0.1-mm defect did not lead to lithium plating; however, such a defect was minimally noticeable.
