Battery cell for electric vehicle battery pack

A method of providing electrical power to electric vehicles via battery cells of a battery packs, comprising:

• providing a battery pack having a battery cell, the battery call having a housing that includes a first end and a second end and defining an inner region;
• disposing an electrolyte in the inner region defined by the housing;
• coupling a lid to the first end of the housing, the lid including a first polarity portion, a second polarity portion and a first isolation layer disposed between the first polarity portion and the second polarity portion, the second polarity portion coupled with the first end of the housing;
• and
• electrically coupling, through a first polarity tab, the electrolyte with the first polarity portion of the lid, the first polarity tab including a spring element to apply a force at a predetermined level to the electrolyte.
