Abstract
An electrochemical cell having a cell housing that contains an active anode material and an active cathode material. An electrically conductive current collector member within the cell housing is in electrical contact with one of the active materials, and an electrically conductive pin member having a first portion protrudes from the cell through an orifice in the cell housing. A sealing member is disposed in the the orifice between the pin member and the cell housing to seal the interior of the cell from its surroundings. A second portion of the electrically conductive pin member is both releasably secured within an aperture in the current collector member and in electrical contact with the current collector member, so that when the pressure within the cell exceeds a predetermined pressure limit, the pin member is ejected from the cell and the excessive internal pressure is then vented.
