Battery cells for battery packs in electric vehicles

A method of providing battery cells for battery packs of electric vehicles, comprising:

• forming a housing for a battery cell including a body region, a neck region, and a head region;
• housing, within the body region, an electrolyte, a first electrode, and a second electrode;
• arranging a sealing element within the head region, the sealing element supported by a shoulder portion of the neck region;
• disposing a first conductive layer within the sealing element, the first conductive layer including a first polarity terminal to electrically couple with a first bonding element connected to the first electrode, the first conductive layer defining a first opening to pass a second bonding element;
• disposing a second conductive layer within the sealing element, the second conductive layer including a second polarity terminal to electrically couple with the second bonding element connected to the second electrode, the second conductive layer defining a second opening to pass the first bonding element, the second opening located in an offset position from the first opening;
• and
• including an insulation layer in at least part of a space defined by the first conductive layer, the second conductive layer, and the sealing element.
