Dual polarity lid for battery cell of an electric vehicle

A method of providing a battery cell of a battery pack to power an electric vehicle, the method comprising:

• providing a battery pack having a battery cell, the battery cell having a housing that includes a first end and a second end and defines an inner region;
• disposing an electrolyte in the inner region defined by the housing;
• and
• coupling a lid with a first end of the housing, coupling the lid comprises:
• providing a first polarity layer having a first polarity orifice and a scored region;
• coupling an insulating layer with at least one surface of the first polarity layer, the insulating layer having a first insulated orifice and a second insulated orifice;
• coupling a second polarity layer with at least one surface of the insulating layer such that the insulating layer is disposed between the first polarity layer and the second polarity layer to electrically insulate the first polarity layer from the second layer;
• disposing a protruding second polarity region of second polarity layer through the first insulated orifice of the insulating layer and the first polarity orifice of the first polarity layer, the second polarity region having a second polarity orifice;
• aligning the second polarity orifice of the second polarity region with the scored region of the first polarity layer and the second insulated orifice of the insulating layer;
• and
• crimping at least one edge of a gasket over edge surfaces of each of the first polarity layer, the second polarity layer, and the insulating layer to couple the first polarity layer, the second polarity layer, and the insulating layer together.

An electric vehicle, comprising:

• a battery pack having a battery cell, the battery cell comprising:
• a housing having a first end and a second end, the housing defining an inner region;
• an electrolyte disposed in the inner region defined by the housing;
• a lid coupled with a first end of the housing, the lid comprising:
• a first polarity layer having a first polarity orifice and a scored region;
• an insulating layer having a first insulated orifice and a second insulated orifice;
• a second polarity layer having a protruding second polarity region that extends through the first insulated orifice of the insulating layer and the first polarity orifice of the first polarity layer;
• the second polarity layer having a second polarity orifice, the second polarity orifice aligned with the scored region of the first polarity layer and the second insulated orifice of the insulating layer;
• the insulating layer disposed between the first polarity layer and the second polarity layer to electrically insulate the first polarity layer from the second layer;
• and
• a gasket coupled with edge surfaces of each of the first polarity layer, the second polarity layer, and the insulating layer, the gasket holds the first polarity layer, the second polarity layer, and the insulating layer together.
