Abstract
A process for assembling an electrochemical cell that utilizes an electrode containment shield to prevent internal electrical short circuits that are caused by fragments of a frangible electrode coming into contact with the battery's opposing electrode. The shield, which may be secured to the current collector, is particularly useful with low volume seals that do not support the separator.
