ABSTRACT:
A sealed, through partition terminal for an electrochemical cell featuring the use of gasketing material to prevent the spread of electrolyte past the terminal seal assembly is disclosed. An orifice formed in a lid of an electrochemical cell accepts a terminal member that is secured to the lid with a fastener threaded onto the terminal member. A shoulder molded on the bottom face of the lid and adjacent to the orifice prevents axial movement of the terminal member while torquing the fastener. A gap formed between the wall of the orifice and the terminal member is filled with gasketing material that is compressed by torquing the fastener. The compressed gasketing material seals any gaps between the terminal member and lid orifice preventing electrolyte leakage.
