## (57) ABSTRACT 

A process for producing an electrochemical cell, compris› ing: (A) continuously depositing a wet cathode active mate› rial mixture onto a surface of a cathode current collector to form a cathode electrode, wherein the wet cathode active material mixture contains 30% to 85% by volume of a cathode active material and 0% to 15% by volume of a conductive additive dispersed in a first liquid or polymer gel electrolyte; (B) continuously depositing a wet anode active material mixture onto a surface of an anode current collector to form an anode electrode, wherein the wet anode active material mixture contains an anode active material and a conductive additive dispersed in a second electrolytes; and (C) combining the cathode electrode or a portion thereof and the anode electrode or a portion thereof to form the cell; wherein the anode electrode and/or the cathode electrode has a thickness from 200 µm to 3,000 µm.
