Abstract:
1. An electrochemical cell comprising: a can having a side wall that is coupled to a first end of the can, wherein the can includes a vent at the first end of the can and the vent is configured to tear along a fracture groove to enable gases and/or effluent to exit the can, through the vent, when a first pressure inside the can reaches a first pressure threshold; a cell element within the can; electrolyte within the can; a spring compressed between the cell element and a first side of the vent facing the cell element, wherein the spring is configured to facilitate tearing along the fracture groove after the first pressure reaches the first pressure threshold; and a suppressant container provided adjacent a second side of the vent opposite to the first side, wherein suppressant is contained inside the suppressant container and the vent is configured to open toward the inside of the suppressant container.
