Abstract: In various aspects, the present disclosure provides a method of manufacturing an electrode for an electrochemical cell. The method includes contacting a solid electrode material and a substrate at an interface. The method further includes preparing a liquid electrode material at the interface by heating at least a portion of the solid electrode material to a first temperature. The first temperature is greater than or equal to a melting point of the solid electrode material. The method further includes creating a layer of the liquid electrode material on the substrate by moving at least one of the solid electrode material and the substrate with respect to the other of the solid electrode material and the substrate. The method further includes forming the electrode by cooling the liquid electrode material to a second temperature. The second temperature is less than or equal to the melting point.
