  • Publication number: 20230241705
    Abstract: A method comprises deforming one or more metal foils of a battery between a punch and a die to form bent metal foils. The one or more bent metal foils are disposed in a foil holding fixture with a battery lead disposed next to the one or more bent metal foils such that a bent portion of the one or more bent metal foils are separated from the battery lead by a distance of 0.1 to 2 millimeters. The one or more bent metal foils are impact welded by causing the foils to impact one another or to impact a battery lead at a velocity of speeds of 300 to 900 meters per second.
