Abstract
A method of analyzing the quality of a battery cell includes performing a high-throughput quality check on the battery cell with a quality control system, assessing a quality score to the battery cell, with quality score identifying the battery cell as low-quality or high-quality, and performing a comprehensive quality check on the battery cell if identified as low-quality. The method further includes assessing an enhanced quality score to the battery cell superseding the quality score of the quality control system identifying the battery cell as confirmed low-quality or confirmed high-quality and providing revised production instructions for manufacturing successive battery cells if confirmed low-quality.
