Abstract
An extremely high rate flat cell and a method of fabrication thereof with the cell comprising successive stacked anode and cathode layers within a cell container comprised of two members with co-fitting external flanges. Each cathode layer embodies a metallic extension or tab therefrom for external terminal connection. The extensions of all the cathode layers are substantially symmetrically positioned between said co-fitting external flanges with said flanges and metallic extensions all being simultaneously welded together and electrically interconnected during cell sealing. The anode layers are electrically connected together, preferably by pressure contacting layers to each other adjacent to a metallic terminal member for said anode. Such a cell having a lithium anode, a carbon cathode and a thionyl chloride electrolyte solvent/cathode depolarizer (3" diameter.times.0.90" height) safely provides a short circuit current in excess of 1500 amperes at a voltage above 1 volt and about 14 ampere hours at a constant current of 100 amperes.
