摘要： A vehicle battery includes a pouch cell configured to provide power to at least one power system of a vehicle, and multiple electrode foils stacked together at least partially within the pouch cell. Each of the multiple electrode foils includes a foil extension at an end of the electrode foil, a first group of foil extensions are connected together via a first ultrasonic weld to define a first foil extension weld portion, and a second group of foil extensions are connected together via a second ultrasonic weld to define a second foil extension weld portion.

摘要： A method of making a reference electrode assembly for an electrochemical cell according to various aspects of the present disclosure includes providing a subassembly including a separator layer and a current collector layer coupled to the separator layer. The method further includes providing an electrode ink including an electroactive material, a binder, and a solvent. The method further includes creating a reference electrode precursor by applying an electroactive precursor layer to the current collector layer. The electroactive precursor layer covers greater than or equal to about 90% of a superficial surface area of a surface of the current collector layer. The electroactive precursor layer includes the electrode ink. The method further includes creating the reference electrode assembly by drying the electroactive precursor layer to remove at least a portion of the solvent, thereby forming an electroactive layer. The electroactive layer is solid and porous.

摘要： Composite reference electrode substrates and relating methods are provided. The composite reference electrode substrate includes a separator portion and a current collector portion adjacent to the separator portion. A method for forming the reference electrode substrate includes anodizing one or more surfaces of a first side of an aluminum foil so as to form a porous separator portion disposed adjacent to a porous current collector portion. The porous separator portion includes aluminum oxide, and the current collector portion includes the aluminum foil. The separator portion and the current collector portion each have a porosity of greater than or equal to about 10 vol. % to less than or equal to about 80 vol. %.

摘要： A method of manufacturing a component for a reference electrode assembly according to various aspects of the present disclosure includes providing a separator having first and second opposing surfaces. The method further includes sputtering a first current collector layer to the first surface via magnetron or ion beam sputtering deposition. A porosity of the separator is substantially unchanged by the sputtering. In one aspect, the method further includes sputtering a second current collector layer to the second surface via magnetron or ion beam sputtering deposition. In one aspect, the first current collector layer includes nickel and defines a first thickness of greater than or equal to about 200 nm to less than or equal to about 300 nm and the second current collector layer includes gold and defines a second thickness of greater than or equal to about 25 nm to less than or equal to about 100 nm.
