Abstract
Provided is a separator/cathode assembly for use in an electric current producing cell, wherein the assembly comprises a cathode current collector layer interposed between a first cathode layer and a second cathode layer and a porous separator layer on the side of the first cathode layer opposite to the cathode current collector layer, wherein the first cathode layer is coated directly on the separator layer. Also provided are methods of preparing such separator/cathode assemblies.
