Abstract:
Embodiments are described in terms of selective methods of sealing separators and jellyroll electrode assemblies and cells made using such methods. More particularly, methods of selectively heat sealing separators to encapsulate one of two electrodes for nickel-zinc rechargeable cells having jellyroll assemblies are described. Selective heat sealing may be applied to both ends of a jellyroll electrode assembly in order to selectively seal one of two electrodes on each end of the jellyroll.
