Electric vehicle battery cell

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

• providing a housing for a battery cell of a battery packing having a plurality of battery cells, the housing having a body region and a head region, the head region defining an opening at a lateral end of the housing;
• housing, within the body region, an electrolyte, a first electrode, and a second electrode;
• disposing, in the opening defined by the head region, a first sealing element defining a first slot and a second slot;
• arranging, in the first slot defined by the first sealing element, a second sealing element defining a first opening for a first polarity terminal;
• arranging, in the second slot defined by the second sealing element, a third sealing element defining a second opening for a second polarity terminal;
• disposing, in the first opening defined by the second sealing element, a first conductive element including the first polarity terminal to electrically couple with a first bonding element connected to the first electrode;
• disposing, in the second opening defined by the third sealing element, a second conductive element including the second polarity terminal to electrically coupled with a second bonding element connected to the second electrode, the second conductive contact electrically isolated from the first conductive contact;
• disposing, between the second sealing element and the first electrode, a first protector to react during a first failure condition that occurs within the body region;
• and
• disposing, between the third sealing element and the second electrode, a second protector to react during a second failure condition that occurs within the body region, the second failure condition different from the first failure condition.
