Abstract 1. An air-depolarized primary battery comprising an electrolyte solution, an anode in said solution, a carbon cathode partially immersed in said solution and having a plurality of vertical cavities therein extending through the top face thereof to the bottom portion thereof, said cavities being cylindrically shaped, a helix wire of a conductive spring material inserted in each of said cavities throughout the length thereof, each of said wire helices having normally a larger outside diameter than the diameter of said respective cavity causing the wire helix to exert a radial pressure against the wall of the cavity and provide a continuous firm engagement of the helix on a helical line with said cathode, a terminal post anchored into an upper portion of said cathode between said cavities in electrically conductive relationship with the cathode, a lead wire extending from and electrically connected to each of said wire helices, and means electrically connecting each of said lead wires to said terminal post.
