Abstract
An end cap assembly for an electrochemical cell having an end cap, a current collector, and a seal. The end cap has a top surface and a bottom surface. The current collector has a columnar body with a head at one end thereof. The seal has a central boss with an opening through which the current collector is inserted. The seal also has a peripheral edge and a connecting part connecting the central boss with the peripheral edge. The connecting part of the seal has a top surface and a bottom surface. The central boss has a top surface and a bottom surface. The top surface of the central boss faces the bottom surface of the end cap and the bottom surface of the central boss does not extend below the bottom surface of the connecting part. The current collector is positioned within the opening of the central boss so that the head of the current collector does not touch the top surface of the central boss thus forming a gap from about 0.01 mm to about 0.50 mm between the head of the current collector and the top surface of the central boss. The head of the current collector is electrically connected to the bottom surface of the end cap.
