1. A method of making a separator/anode assembly for use in an electric current producing cell comprising the steps of:
providing a porous separator layer;
coating a first anode layer comprising solvent(s), anode active material in particle form, and electrically conductive carbon particles directly on said porous separator layer; and
depositing an anode current collector layer on the anode layer, so as to make the separator/anode assembly.
