Abstract
Disclosed are safe, easy to manufacture prismatic cells having scored regions strategically located on portions of the prismatic cell can or cell header. When they are located on the cell can, the scored regions are provided on the side of the can, rather than on the bottom of the can as in other designs. The scored region may be located on a corner of one side of the side of the cell can. Scored regions so located tend to release excess pressure over a relatively narrow and easier to control pressure range. Similar benefits can be obtained by placing the scored region on a 'dished' header of a prismatic cell. Such dished header designs have a vertical lip around the perimeter of a substantially flat horizontal portion. The scoring may be provided near one of the ends of the header's substantially flat portion.
