Abstract
An electrode assembly for an air depolarized cell in which an electrical conducting tab is mechanically attached to the electrode assembly to produce a low resistance electrical connection. The tab includes a crown which has sharp tines thereon for piercing the electrode assembly which generally comprises a separator, a current collecting screen, an electrode material and an outer hydrophobic member. The projections on the conducting tab are wide enough to insure that each of the tines will engage a section of current collecting screens.
