Abstract
A reserve type electrochemical cell has its liquid cell component left separate in a rupturable envelope separate from the battery stack. The envelope is located within a sleeve in a well at the center of the battery stack. Piercing means are arranged in recesses along the side of the sleeve. If the cell is spun about its axis, the liquid cell component forces the part of the envelope into the recesses where it is ruptured, thereby discharging the liquid cell component into the battery stack.
