Abstract

The present disclosure generally pertains to production of rechargeable battery cells, commonly called secondary cells. More specifically, the disclosure relates to inline gas analysis measurements in a formation process for secondary cells. According to a first aspect the disclosure relates to an arrangement 2 for inline gas analysis measurements in a formation process for secondary cells 1. The arrangement 1 comprises a gas analysis container 22, a plug extraction mechanism 21, and a gas analyser 27. The gas analysis container comprising a sample inlet 23 designed to form fluid tight connection to an opening 12 of a secondary cell 1 to be tested, and an outlet 26. The plug extraction mechanism designed to pull a plug 11 arranged to seal the opening 12, while the opening 12 is connected to the sample inlet 23 of the gas analysis container 22, whereby formation gas residing inside the analysis container 22 is exhausted through the opening 12 and flows into the gas analysis container 22. The gas analyser 27 arranged to be connected to the outlet 26 of the gas analysis container, whereby gas spectra of the formation gas in the analysis container can be analysed. The disclosure also pertains to a corresponding method.
