1. An electrochemical cell comprising:
(a) an electrode comprising a layered material having a plurality of layers, each of the layers comprising a substantially two-dimensional ordered array of cells having an empirical formula of Mn+1Xn,
wherein M comprises a transition metal selected from the group consisting of a Group IIIB metal, a Group IVB metal, a Group VB metal, a Group VIB metal, and any combination thereof
wherein X is CxNy wherein x+y=n, and
wherein n is equal to 1, 2, or 3 and
(b) an electrolyte, wherein the electrolyte comprises a room-temperature ionic liquid or wherein the electrolyte comprises a deep eutectic solvent,
wherein the plurality of layers lacks terminal halide or oxygen surface functionality.
