Claim 0:
1. An electrochemical device comprising:
a current collector;
a solid electrode disposed on the current collector, wherein the solid electrode comprises one or more alkali metals; and
an interfacial layer comprising an alloy disposed on the solid electrode, wherein the alloy comprises one or more alkali metals, wherein at least one alkali metal of the solid electrode and at least one alkali metal of the alloy are a same alkali metal such that the solid electrode and the alloy include different proportions of the same alkali metal, wherein the alloy comprises either: (i) a liquid phase when the alloy is at a temperature between or equal to 15° C. and 30° C.; or (ii) a solid phase and the liquid phase when the alloy is at the temperature between or equal to 15° C. and 30° C., and wherein the electrochemical device is configured such that the interfacial layer is disposed at an interface between the solid electrode and an electrolyte.
