Abstract:
1. A process for assembling an electrochemical cell, comprising the steps of: (a) providing a cylindrical open ended container comprising a first electrode defining a tubularly shaped cavity, a separator lining said cavity, and a second electrode disposed within said separator lined cavity, said second electrode comprising a frangible composition including particulate zinc; (b) producing a current collector assembly comprising a cover, an electrode containment shield having a width less than the inside diameter of said container's open end and an elongated electrically conductive member having a first end and a second end, said step of producing a current collector assembly comprising contacting an end of said electrically conductive member to said cover and inserting an end of said electrically conductive member perpendicularly through a disc shaped electrode containment shield thereby forming a preassembled current collector assembly, said first end of said electrically conductive member contacts said cover, said second end of said electrically conductive member forms a freestanding end that extends from said shield; and (c) joining said preassembled current collector assembly and said open ended container by inserting said second end of said assembly's conductive member into said second electrode and securing said current collector assembly to the open end of said container whereby said electrode containment shield is positioned between said cover and said second electrode.
