Dey, A N

Abuse resistant electrochemical cells are described having consumable fluid depolarizer/electrolyte solvents, active metal anodes and inactive conductive cathodes which are made resistant to abusive forced discharge or cell reversal conditions by maintaining excess portions of both the fluid depolarizer/electrolyte solvent with electrolyte and the active metal anode at the end of cell discharge. The remaining portion of the active metal is electrically connected to the negative terminal of the cell and substantially faces the entire surface of the originally adjacent inactive cathode. The remaining portion of the fluid depolarizer/electrolyte solvent is sufficient for maintaining electrical and thermal conductivity whereby heat concentration is prevented.
