Abstract

A method for measuring gases generated by at least a portion of a battery cell includes arranging a test sample in a chamber. The test sample comprises one of a battery cell including terminals and a gas port and a test fixture including terminals and a gas port and housing at least a portion of a battery cell. The method includes connecting the gas port of the test sample to a node; supplying a carrier gas at a known pressure and flow rate to the node; sampling gas at or downstream from the node using at least one of a mass spectrometer and a gas analyzer; and determining concentrations of gases in the test sample using the at least one of the mass spectrometer and the gas analyzer.
