Abstract

A lithium dioxide cell construction including a resettable positive temperature coefficient fuse. The positive temperature coefficient fuse, can withstand shock and mechanical vibration without damage and is mounted in such a way that it cannot be bypassed without destroying the cell. If the cell is shorted out, within a few seconds, the positive temperature coefficient fuse limits the fault current to a low value, which will never allow the cell to overheat or vent.
