Patent number: 11757082Abstract: 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.Type: GrantFiled: February 19, 2021Date of Patent: September 12, 2023Assignee: GM Global Technology Operations LLCInventors: Jin Liu, Jiazhi Hu, Raffaello Ardanese, Ryan C.

Publication number: 20230178816Abstract: 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.Type: ApplicationFiled: December 7, 2021Publication date: June 8, 2023Inventors: Raffaello Ardanese, Thomas A.
