between the two screen backed cathode collector members arranged in a container as shown in fig1 and 2 the inserted conductive spring strip 28 resiliently biases the two cathode collector members 14 and 20 via backing screens 15 and 17 so as to provide a substantially uniform and continuous pressure over the inner wall of the cathode collector members the extended end 30 of spring strip 28 is shown projected above the surface of anode members 14 and 20 an insulating gasket 36 has a central opening 38 through which the projected end 30 of the spring strip 28 passes whereupon the end 30 is then welded to a cover 40 thereby adapting the cover 40 as the cathodic or positive terminal of the cell secured to the cover 40 is a cylindrical cap 42 specifically the cylindrical cap comprises a cylindrical segment 41 terminating at one end with an outwardly oriented flange 44 which is secured to cover 40 the insulating gasket 36 has a peripheral depending skirt 52 disposed between the cover 40 and the upper inner wall of the container 2 for closing the cell through conventional crimping techniques as shown in fig1 the cylindrical cap is secured to the cover 40 and the cell is closed using conventional crimping techniques with all of the solid components of the cell assembled within the container 2 after the cell is assembled with the solid.
