Abstract
This invention includes a spacer, preferably having a cross section resembling the letter “T”, that is positioned between the electrode assembly and the metal can in electrochemical battery cells. The spacer allows a void to exist between the corner of the metal can and the electrode assembly. This “crumple zone” prevents any external damage to the can from damaging the internal electrode assembly. The invention facilitates passage of common OEM drop testing without compromising cell performance. The invention increases the reliability of the cell by allowing the cell to resist external impacts.
