Resilient mandrel for battery electrode assembly |
| abstract |
An improved electrode assembly (16) for batteries and the like including a central mandrel (20) configured to exert a resilient outward force on a multilayer web (18) wound around the mandrel. The multilayer web includes a positive electrode layer, a negative electrode layer, and a separator layer separating the positive and negative layers. The resilient outward force acts to maintain the tightness of the web roll, thus lowering electrical resistance and enhancing battery cycle life. The mandrel is preferably formed of sheet metal configured to define an S-shape having a central section and first and second resilient leaves (40, 42) extending therefrom. The leaves preferably define substantially planar areas for bearing against an inner turn of the web roll to exert a resilient outward thereagainst. |
