An electrochemical cell having a temperature-activated vent in series with a pressure-activated vent. The inner cover of the inner cell housing has an upstanding rim around a central pressure release vent. The outer cover that closes the outer cell container has an annular area pressed against this rim and sealed to the rim by a heat fusible solder to form a temperature-responsive vent mechanism in series with the pressure-responsive vent.
