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.
