Elektrokemisk celle bestående af ultratynde film

摘要

This invention relates to electrochemical cells having superior recharge and discharge capabilities and to a method for the production of the cells. The cells are characterized by the use of ultra-thin non-perforated negative and positive films (18) of lead or nickel to be used in lead acid and nickel cadmium systems. The method includes the use of a single sheet of separator material (12) that has been infiltrated with electrolyte prior to its spiral winding onto a mandrel.
