1. A method of manufacturing an electrode for an electrochemical cell, the method comprising:
contacting a solid electrode material and a substrate at an interface;
preparing a liquid electrode material at the interface by heating at least a portion of the solid electrode material to a first temperature greater than or equal to a melting point of the solid electrode material;
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; and
forming the electrode by cooling the liquid electrode material to a second temperature less than or equal to the melting point.
