ABSTRACT:
An active metal non-aqueous electrochemical cell including a lithium anode, an organic electrolyte system, a cathode contained in a cell housing, and at least one hermetically sealed pin-type lead extending through a cell header is provided with an hermetically sealed, pressure and/or temperature actuated, snap-action header diaphragm disconnect mechanism fixed to, and which snaps outward to disconnect, the pin terminal from the internal cell lead in response to elevated internal pressure reaching a sufficient amount to operate the snap-action mechanism. The position of the snap-action header diaphragm is visible outside of the cell.
