A capacitor has a first side and an opposite second side. The capacitor also includes a first conductive member having a first planar surface and a first side edge, a first electrical connection extending from the first conductive member adjacent the first side. A second conductive member has a second planar surface. The second planar surface is spaced apart from and parallel to the first planar surface of the first conductive member. The second planar surface and the first planar surface define a space therebetween. The second conductive member also includes a third planar surface that is spaced apart from and disposed parallel to the second planar surface opposite from the first planar surface. A second electrical connection extends from the second planar surface adjacent the first side. The second conductive member also includes an electrically conductive portion, disposed adjacent the second side, electrically connecting the second planar surface and the third planar surface. A polymer electrolyte is disposed in the space defined by the first planar surface and the second planar surface. The polymer electrolyte is in contact with at least a portion of the first planar surface and at least a portion of the second planar surface.

Capacitor with folded end plate tab configuration

A hybrid cell/capacitor assembly (300) includes a battery cell (100) and a capacitor (200) formed into a thin rectangular sheet and having two leads (205, 210) extending therefrom. The capacitor (200) is wrapped around the battery cell (100) to form the hybrid cell/capacitor assembly (300). The leads (205, 210) of the capacitor (200) can be attached to terminals (105, 100) of the battery cell (100) or to terminals of one or more other cells within a battery pack (600).
