Abstract

See full text

Aspects of the disclosure include degas equipment and degassing process schemes for providing high throughput extraction of battery cell formation gas. An exemplary method can include loading a battery cell in a sampling chamber of a degas station and creating an opening in the battery cell to release formation gas. A first portion of the formation gas can be routed to a collection chamber of the degas station while the formation gas is prevented from venting. After routing the first portion of the formation gas to the collection chamber, a second portion of the formation gas can be vented until degassing is complete. The first portion of the formation gas can be diluted with a dilution fluid and the diluted first portion of the formation gas can be routed to a cell quality control gas manifold configured to measure battery cell formation gas compositions.
