Abstract: Methods for fabricating an anode, methods for fabricating a battery, and lithium batteries are disclosed. A method for fabricating an anode includes forming a melt comprising lithium and a surface tension reduction agent, wherein the surface tension reduction agent is selected from the group consisting of silver, tin, gallium, indium, zinc, and combinations thereof; and contacting an anode current collector with the melt, wherein a layer of the melt wets onto the anode current collector to form the anode as a lithium alloy.
