    Abstract: 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.

    Abstract: A method for fabricating an anode for a lithium ion battery cell is described and includes forming a solid electrolyte interface (SEI) layer on a raw anode prior to assembly into a battery cell by applying a first SEI-generating electrolyte to the raw anode to form a first intermediate anode, applying a second SEI-generating electrolyte to the first intermediate anode to form a second intermediate anode, and applying a third SEI-generating electrolyte to the second intermediate anode to form a cell anode, wherein the cell anode includes the raw anode having the SEI layer. Thus, a cell anode is formed by sequentially applying SEI-generating electrolytes to a raw anode to form the cell anode with an SEI layer, and a lithium ion battery cell is formed by assembling the cell anode into a cell pack, with a cathode, and a separator, and adding a cell electrolyte prior to sealing.

    Abstract: A method of managing a selective catalytic reduction system of a motor vehicle. During a first predetermined time period, a plurality of functionality checks of the sensor are performed for identifying if the sensor is able to provide a reliable measurement of the ammonia concentration. During the same first predetermined time period, a plurality of values of the ammonia concentration in the diesel exhaust fluid is measured by the sensor. A maintenance inducement strategy of the selective catalytic reduction system is activated if each of the values of the ammonia concentration measured during the first predetermined time period is smaller than a predetermined threshold value, and if each of the functionality checks of the sensor performed during the same first predetermined time period identifies that the sensor is able to provide a reliable measurement of the ammonia concentration.
