Battery and method of allowing for volumetric expansion of battery cells within a battery

Abstract

A battery having a first battery cell and a second battery cell with a spacer located between the first and second battery cells. The spacer comprises a polymer layer and one or more foam elements which are positioned in a substantially vertical direction on the polymer layer. The foam elements are positioned on the polymer layer to permit volumetric expansion of the battery cell. A method for allowing for volumetric expansion of battery cells within a battery. The method comprises placing a spacer between a first battery cell and a second battery cell. The spacer comprises a polymer layer and one or more foam elements positioned substantially vertically on the polymer layer so as to permit volumetric expansion of the battery cell.
