Abstract
An electrochemical cell is provided that has a negative terminal cover with a hole therein or a raised portion with notches therein to provide adequate air ingress during the coating of a non-conductive material on the raised portion of the negative terminal. The addition of the hole or notches in the negative terminal cover prevents a vacuum from forming and thereby prevents migration of the non-conductive material toward the center of the negative terminal cover. The process of making an electrochemical cell with a negative terminal cover that has a hole therein or has a raised portion with notches therein is also provided.
