ABSTRACT:
An abuse resistant electrochemical cell having an active metal anode, a fluid cathode depolarizer, an inert cathode and an electrolyte solution. The cell components are arranged in terms of relative capacities and configuration such that a sufficient amount of the dischargeable anode metal is utilized prior to the cell reaching zero volts (caused by deactivation of the cathode) whereby, upon forced discharge, polarization of both anode and cathode and deep cell reversal occur within a short period of time thereafter. This short period of time is no greater than 15% of the initial discharge time to zero volts. The cell additionally contains sufficient fluid depolarizer such that a portion thereof remains at the time of such deep cell reversal.
