Abstract
A quality control system analyzes the quality of a battery cell, with the battery cell defining a gas pouch configured to expand from a deflated configuration to an inflated configuration when filled with a gas formed during a cell formation process. The system comprises a computational system comprising a processor and a memory and a measurement instrument in electronic communication with the computational system. The measurement instrument is arranged to measure a distance defined by the gas pouch and transmit a signal to the computational system corresponding to the distance. The computational system is arranged to analyze the distance with the processor and determine a volumetric measurement of the gas within the gas pouch and compare the volumetric measurement to a threshold in the memory to assess a quality score for the battery cell. A corresponding method analyzes the quality of the battery cell with the quality control system.
