1. A quality control system for analyzing the quality of a battery cell, with the battery cell defining a gas pouch configured to be filled with a gas formed during a cell formation process of the battery cell, the quality control system comprising:
a computational system comprising a processor and a memory; and
a manifold defining a passageway extending between an inlet port configured to be in fluid communication with the gas pouch for receiving the gas and an outlet port in fluid communication with the inlet port through the passageway and configured to exhaust the gas from the manifold; and
at least one sensor coupled to the manifold and in fluid communication with the passageway, with the sensor in electronic communication with the computational system, and with the sensor arranged to measure a physical property of the gas removed from the gas pouch and transmit a signal to the computational system corresponding to the physical property of the gas;
wherein the computational system is arranged to analyze the physical property of the gas with the processor and access a threshold value corresponding to the physical property stored in the memory to compare the physical property to the threshold value and assess a quality score for the battery cell.
