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. An orifice formed in an inner lid of an electrochemical cell accepts a terminal member that is secured to the inner lid with a fastener threaded onto the terminal member. A shoulder molded on the bottom face of the inner 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 inner lid orifice preventing electrolyte leakage.

A method of making a terminal seal comprising: coating with gasketing material a terminal having a top portion, a bottom portion and axially disposed external threading on said top portion, an inner top having a bottom surface, a top surface, at least one side and a portion defining an orifice sized to receive said terminal and a fastener having a portion defining a fastener orifice with internal threading axially disposed on said portion defining said fastener orifice sized to matingly receive said terminal; inserting said terminal coated with said gasketing material through said top orifice from said bottom surface of said inner top; placing said fastener onto said terminal top portion with said internal and external threading matingly aligned; torquing said fastener onto said terminal to releasably secure said terminal and to compress said gasketing material while in an uncured state; and restricting radial and axial travel of said gasketing material with the combination of said terminal, said fastener and said inner top.
