Abstract
A multi-fold rechargeable battery cell structure comprising electrode elements and separator elements, wherein relief slots are formed along the fold axes of the outermost electrode elements in order to relieve folding stresses which could result in damage and impairment of the operation of the cell. The slots are formed adjacent to regions of intact electrode material in each outermost electrode element and are arranged such that the slots of one electrode element are aligned with the regions of intact electrode material of the other electrode element. In this manner, electrode element planar integrity is maintained while the effective laminate fold region thickness is reduced.
