The present invention improves the performance of lithium electrochemical cells by providing a new electrode assembly based on a sandwich cathode design, but termed a double screen sandwich cathode electrode design. In particular, the present invention uses sandwich cathode electrodes which are, in turn, sandwiched between two half double screen sandwich cathode electrodes, either in a prismatic plate or serpentine-like electrode assembly. In a jellyroll electrode assembly, the cell is provided in a case-positive design and the outside round of the electrode assembly is a half double screen sandwich cathode electrode.
