Abstract
Single cell laminated polymeric rechargeable battery sheets are folded in irregularly alternating directions about parallel fold axes to provide battery cell structures presenting available terminal locations requiring reduced collector element current travel distance to thereby significantly reduce battery impedance. An embodiment enables the use of equilateral cell sheets which are folded about orthogonal axes in two dimensions to yield battery cells with exceptionally high ratios of active area to collector-origin impedance.
